The signal processing method, the indication method, the device, the communication equipment and the readable storage medium provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart of a signal processing method according to an embodiment of the present application, where the method is applied to a signal receiving end, and the signal receiving end is not limited to this. As shown in fig. 1, the method comprises the steps of:
step 11: a received signal threshold value is determined.
In this embodiment, since the probability that the transmission signal is distributed around the upper and lower threshold values is large, the threshold value of the reception signal can be determined according to the information related to the threshold value of the transmission signal. Further, the received signal threshold value may be determined according to information related to the transmitted signal threshold value and related parameters of the signal receiving end, such as path loss, path loss factor, and the like.
Step 12: and setting the value of the first received signal to be the received signal threshold value according to the received signal threshold value, wherein the value of the first received signal exceeds a signal value range defined by the received signal threshold value.
In this embodiment, the value of the received signal, such as the value of the first received signal, may be selected as a power value, an intensity value, etc., which is not limited.
Optionally, the received signal threshold value may include at least one of: an upper threshold value of the received signal and a lower threshold value of the received signal.
In some embodiments, when the received signal threshold is an upper threshold of the received signal, if the value of a certain received signal exceeds a signal value range defined by the upper threshold, the value of the received signal may be directly set as the upper threshold.
In some embodiments, when the received signal threshold is a lower threshold of the received signal, if the value of a certain received signal exceeds a signal value range defined by the lower threshold, the value of the received signal may be directly set as the lower threshold.
In some embodiments, when the received signal threshold includes an upper threshold and a lower threshold of the received signal, if the value of a certain received signal exceeds a signal value range defined by the upper threshold, the value of the received signal may be directly set as the upper threshold; and/or if the value of a certain received signal exceeds the signal value range defined by the lower threshold value, the value of the received signal can be directly set as the lower threshold value.
According to the signal processing method, the received signal threshold value can be determined, and the value of the first received signal is set to be the received signal threshold value according to the received signal threshold value, wherein the value of the first received signal exceeds the signal value range defined by the received signal threshold value. Therefore, by setting the value of the received signal, partial noise can be filtered, and the interference of the noise to the signal can be relieved, so that the signal-to-noise ratio of the signal receiving end is improved, the anti-noise capability of a communication system is further improved, and the communication coverage distance is increased.
For example, referring to fig. 2, fig. 2 is a front-to-back comparison of noise filtering using the scheme in the embodiment of the present application. In fig. 2, the dc-biased optical DCO signal is quadrature phase shift keying (Quadrature Phase Shift Keying, QPSK) modulated and subjected to clipping (clipping) operations; the asymmetrical amplitude-limited optical ACO signal adopts 16 quadrature amplitude modulation (Quadrature Amplitude Modulation, QAM) modulation and carries out the clipping operation; the layered asymmetric clip light LACO signal adopts 16QAM modulation and performs clipping operation. When the present scheme is not adopted for signal processing at the receiving end, the curves of the changes of Bit Error Rate (BER) and path loss (path) of the DCO signal, the ACO signal and the LACO signal are shown as solid lines in fig. 2. When the scheme is adopted for receiving end signal processing, the change curves of error rates of DCO signals, ACO signals and LACO signals along with path loss are shown as dotted lines in fig. 2. As can be seen from the simulation result of fig. 2, when the ACO signal and the LACO signal are processed by the receiving end signal, the path loss tolerance under the same error rate is improved, and when the DCO signal is processed by the receiving end signal, the error rate is improved without effect, because the ACO signal and the LACO signal have more signals with signal values of 0, and are interfered by channel noise and receiver noise more. That is, according to the scheme in the embodiment of the application, part of noise can be filtered, interference of the noise on signals is relieved, and anti-noise capability of a communication system is further improved.
In the embodiment of the present application, in order to accurately determine the received signal threshold value, the received signal threshold value may be determined according to the threshold indication signaling sent by the signal sending end.
Optionally, the determining the received signal threshold value may include: firstly, receiving a threshold indication signaling from a signal transmitting end; wherein the threshold indication signaling is used for indicating information related to a threshold value of a transmission signal; then, a received signal threshold value is determined based on the threshold indication signaling.
In some embodiments, the received signal threshold value may be determined according to threshold indication signaling sent by the signal sending end and related parameters of the signal receiving end, such as path loss, path loss factor, and the like.
Optionally, the threshold indication signaling may be used to indicate at least one of:
transmitting a signal threshold value;
a first difference between the transmit signal threshold value and an average value (e.g., average power, average strength value, etc.) of the transmit signal;
a ratio of a first difference between a transmitted signal threshold value and an average value (e.g., average power, average intensity value, etc.) of the transmitted signal to the average value of the transmitted signal.
Optionally, when the threshold indication signaling indicates the signal threshold, the signal receiving end may calculate the received signal threshold according to the signal threshold and the path loss between the signal receiving end and the signal sending end. I.e. according to the transmitted signal threshold value and the corresponding path loss, calculating to obtain the attenuated received signal threshold value.
For example, assuming that the threshold value of the transmission signal is T1 and the path loss factor between the signal receiving end and the transmitting end is Y, then: the received signal threshold value is equal to T1 x Y.
In some embodiments, if the threshold indication signaling received by the signal receiving end indicates a threshold value of a transmission signal and the threshold value is 0, then: the signal receiving end can obtain the received signal threshold value of 0 without calculation, and uses the value of 0 to directly process signals.
In some embodiments, if the threshold indication signaling received by the signal receiving end indicates a threshold value of a transmission signal, and the threshold value is 1, and the corresponding path loss factor is 0.5, then: the received signal threshold is equal to the transmitted signal threshold 1 times the path loss factor 0.5, equal to 0.5.
Optionally, when the threshold indication signaling indicates a first difference value between the threshold value of the transmission signal and the average value of the transmission signal, the signal receiving end may calculate a second difference value between the threshold value of the reception signal and the average value of the reception signal according to the first difference value and the path loss between the signal receiving end and the signal transmitting end; then, a received signal threshold is calculated based on the second difference and the average value of the received signal. That is, after the second difference of the attenuated receiving end is calculated according to the first difference and the corresponding path loss, the threshold value of the received signal is calculated according to the second difference and the average value of the received signal.
For example, assuming that the average value of the transmission signal is S1, the threshold value T1 of the transmission signal is S1-T1, the path loss factor between the signal receiving end and the transmitting end is Y, and the average value of the reception signal is S2, then: the first difference value S1-T1 is multiplied by the corresponding path loss factor Y to obtain a second difference value (S1-T1) x Y, and then the second difference value (S1-T1) x Y is subtracted from the average value S2 of the received signal to obtain the received signal threshold value.
In some embodiments, if the threshold indication signaling received by the signal receiving end indicates a first difference value, and the first difference value is 1, the corresponding path loss factor is 0.5, and the average value of the received signal is 1.5, then: the second difference between the received signal threshold value and the average value of the received signal is equal to the first difference 1 multiplied by the path loss factor 0.5, and is equal to 0.5; further, the received signal threshold value is equal to 1.5, the average value of the received signals minus the second difference value of 0.5, and is equal to 1.
Optionally, when the threshold indication signaling indicates a ratio of the first difference to the average value of the transmitted signal, the signal receiving end may calculate, according to the ratio and the average value of the received signal, a third difference between the threshold value of the received signal and the average value of the received signal, for example, by multiplying the ratio by the average value of the received signal to obtain the third difference; then, a received signal threshold is calculated based on the third difference and the average value of the received signal.
For example, assuming that the average value of the transmission signal is S1, the threshold value of the transmission signal is T1, the first difference is S1-T1, the ratio of the first difference to the average value of the transmission signal is B, and the average value of the reception signal is S2, then: the ratio B is multiplied by the average value S2 of the received signal to obtain a third difference b×s2, and then the average value S2 of the received signal is subtracted by the third difference b×s2 to obtain the received signal threshold.
In some embodiments, if the threshold indication signaling received by the signal receiving end indicates a ratio of the first difference value to the average value of the transmitted signal, and the ratio is 0.5, and the average value of the received signal is 1, then: the third difference between the received signal threshold and the average value of the received signal is equal to the average value of the received signal, 1, multiplied by the ratio of 0.5, and equal to 0.5; further, the received signal threshold value is equal to the average value 1 of the received signals minus the third difference value 0.5, which is equal to 0.5.
In this embodiment of the present application, the signal receiving end may determine whether to use the received signal threshold value to process the value of the received signal according to the indication of the signal sending end, or may determine whether to use the received signal threshold value to process the value of the received signal according to whether the signal sending end sends the threshold indication signaling. For example, if the signal transmitting end transmits the threshold indication signaling, the value of the received signal is processed by using the threshold value of the received signal; otherwise, if the threshold indicates that the signaling is default, the value of the received signal is not processed by using the threshold value of the received signal.
Alternatively, the signal receiving end may receive a first signaling from the signal transmitting end, where the first signaling is used to indicate whether to use the received signal threshold value to process the value of the received signal, so that the signal receiving end decides whether to use the received signal threshold value to process the value of the received signal.
Further, the step 12 may include: when the first signaling indicates that the value of the received signal is processed using the received signal threshold value, the value of the first received signal is set to the received signal threshold value according to the received signal threshold value.
Referring to fig. 3, fig. 3 is a flowchart of an indication method provided in an embodiment of the present application, where the method is applied to a signal transmitting end, and the signal transmitting end is not limited to this, for example, a terminal or a network side device. As shown in fig. 3, the method comprises the steps of:
step 31: and transmitting a threshold indication signaling to the signal receiving end, determining a received signal threshold value by the signal receiving end according to the threshold indication signaling, and setting the value of the first received signal as the received signal threshold value according to the received signal threshold value.
Wherein the threshold indication signaling is used for indicating information related to the threshold value of the transmission signal. The value of the first received signal exceeds a signal value range defined by a received signal threshold value.
In this embodiment, the value of the received signal, such as the value of the first received signal, may be selected as a power value, an intensity value, etc., which is not limited.
Optionally, the received signal threshold value may include at least one of: an upper threshold value of the received signal and a lower threshold value of the received signal.
In some embodiments, when the received signal threshold is an upper threshold of the received signal, if the value of a certain received signal exceeds a signal value range defined by the upper threshold, the value of the received signal may be directly set as the upper threshold.
In some embodiments, when the received signal threshold is a lower threshold of the received signal, if the value of a certain received signal exceeds a signal value range defined by the lower threshold, the value of the received signal may be directly set as the lower threshold.
In some embodiments, when the received signal threshold includes an upper threshold and a lower threshold of the received signal, if the value of a certain received signal exceeds a signal value range defined by the upper threshold, the value of the received signal may be directly set as the upper threshold; and/or if the value of a certain received signal exceeds the signal value range defined by the lower threshold value, the value of the received signal can be directly set as the lower threshold value.
According to the indicating method, the threshold indication signaling can be sent to the signal receiving end, the signal receiving end determines the received signal threshold value according to the threshold indication signaling, and the value of the first received signal is set to be the received signal threshold value according to the received signal threshold value, and the value of the first received signal exceeds the signal value range defined by the received signal threshold value. Therefore, by setting the value of the received signal, partial noise can be filtered, and the interference of the noise to the signal can be relieved, so that the signal-to-noise ratio of the signal receiving end is improved, the anti-noise capability of a communication system is further improved, and the communication coverage distance is increased.
Optionally, the threshold indication signaling may be used to indicate at least one of:
transmitting a signal threshold value;
a first difference between the transmit signal threshold value and an average value (e.g., average power, average strength value, etc.) of the transmit signal;
a ratio of a first difference between a transmitted signal threshold value and an average value (e.g., average power, average intensity value, etc.) of the transmitted signal to the average value of the transmitted signal.
Optionally, in the embodiment of the present application, the signal sending end may send a first signaling to the signal receiving end, where the first signaling is used to indicate whether to use the received signal threshold value to process the value of the received signal, so that the signal receiving end decides whether to use the received signal threshold value to process the value of the received signal.
In some embodiments, before the signal transmitting end transmits the first signaling to the signal receiving end, it needs to determine whether to perform signal processing of the receiving end, and transmit the first signaling according to the determination result.
In some embodiments, the value of the first signaling may be selected to be 0 or 1. For example, "0" is used to indicate that the value of the received signal is not processed using the received signal threshold value, and "1" is used to indicate that the value of the received signal is processed using the received signal threshold value; alternatively, "0" is used to indicate that the value of the received signal is processed using the received signal threshold value and "1" is used to indicate that the value of the received signal is not processed using the received signal threshold value.
Optionally, the signal sending end judges whether to perform signal processing of the receiving end according to the following judgment basis: when the proportion of the number of the first transmission signals to the total number of the transmission signals is larger than a first value, determining to use a threshold value of the reception signals to process the value of the reception signals; alternatively, when the ratio of the number of first transmission signals to the total number of transmission signals is less than or equal to the first value, it is determined that the value of the reception signal is not processed using the reception signal threshold value. Wherein the absolute value of the difference between the value of the first transmitted signal and the threshold value of the transmitted signal is less than the second value. The first value and/or the second value may be set based on actual requirements, which is not limited.
For example, a signal transmitting end determines a first value x and a second value y based on actual requirements, obtains a transmitting signal threshold value a according to distribution statistics of transmitting signals, and calculates a proportion z of the number of the first transmitting signals to the total number of the transmitting signals according to a distribution function of the transmitting signals, wherein the absolute value of the difference between the value of the first transmitting signals and the transmitting signal threshold value a is smaller than y; then:
if z is greater than x, the signal transmitting end may set the first signaling to 1, indicate that signal processing by the receiving end is required, and transmit the first signaling to the signal receiving end; alternatively, if z is less than or equal to x, the signal transmitting end may set the first signaling to 0, indicating that signal processing by the receiving end is not required, and transmit the first signaling to the signal receiving end.
In addition, the signal receiving end can determine whether to use the threshold value of the received signal to process the value of the received signal according to whether the signal transmitting end transmits the threshold indication signaling. For example, if the signal transmitting end transmits the threshold indication signaling, the value of the received signal is processed by using the threshold value of the received signal; otherwise, if the threshold indicates that the signaling is default, the value of the received signal is not processed by using the threshold value of the received signal.
It should be noted that, in the signal processing method provided in the embodiment of the present application, the execution body may be a signal processing apparatus, or a control module in the signal processing apparatus for executing the signal processing method. In the embodiment of the present application, a signal processing device is described by taking a signal processing method performed by the signal processing device as an example.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a signal processing apparatus according to an embodiment of the present application, where the apparatus is applied to a signal receiving end, and the signal receiving end is not limited to a terminal or a network side device. As shown in fig. 4, the signal processing device 40 includes:
a first determining module 41, configured to determine a received signal threshold value;
a setting module 42, configured to set a value of a first received signal to the received signal threshold value according to the received signal threshold value; wherein the value of the first received signal exceeds a signal value range defined by the received signal threshold value.
