Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Since how to improve the signal receiving sensitivity of the device is an important aspect of currently improving the signal receiving performance of the device, the signal receiving sensitivity of the device is closely related to the in-band frequency response of the receiving device, and especially for the NBIOT chip/module, the important indexes measuring the receiving performance, namely the receiving sensitivity and the in-band frequency response of the NBIOT chip/module, are closely related. When the frequency response flatness of the device can reach an optimal value, the signal receiving sensitivity of the device can be improved greatly, so that the present disclosure provides a signal receiving method, an apparatus, a storage medium and an electronic device, which can control the frequency response flatness to improve the signal receiving performance of the device. The signal receiving method, apparatus, storage medium, and electronic device will be described in detail below.
Fig. 1 is a flowchart illustrating a signal receiving method according to an exemplary embodiment of the present disclosure. As shown in fig. 1, the method includes step 101 and step 102.
In step 101, a signal is received. The signal may be received through an antenna. The signal is first received by the antenna, and since there are usually many noise in the signal directly received by the antenna, the signal received by the antenna generally needs to be filtered to reduce the noise.
In step 102, controlling filtering of the signal for a preset number of times, so that the bandwidth and the flatness of the signal after filtering can meet preset requirements, wherein the preset number of times is at least three times; wherein at least one of the filters performing the filtering is capable of dynamically adjusting a configuration according to the bandwidth and the flatness of the received signal. When the filtering of the signal received by the antenna is controlled, in order to meet the preset requirement, the filtering of the signal is controlled at least three times, and at least one filter can dynamically adjust the period configuration according to the bandwidth and the flatness of the signal received by the filter, so that the bandwidth and the flatness of the filtered signal can meet the preset requirement. For example, when the filtering of the signal is controlled three times in step 102, the signal receiving method may be performed as shown in fig. 2 as follows.
Fig. 2 is a flowchart illustrating a signal receiving method according to an exemplary embodiment of the present disclosure. As shown in fig. 2, the method includes steps S201 to S203 in addition to step 101 shown in fig. 1.
In step 201, a first filter is controlled to filter the signal, and a first bandwidth and a first flatness of a first filtered signal obtained after filtering are calculated. The filtering effect of this first filter may be fixed by hardware, which acts as a primary filter for the signal, and the filter may be a filter commonly used in radio frequency front-ends, such as SAW (surface acoustic wave filter) or BAW (bulk acoustic wave filter), mainly for filtering unwanted signals on a given frequency path, and mainly for high frequencies.
In step 202, the type of the signal is determined, a filtering mode of a second filter is adjusted according to the type of the signal, the second filter is controlled to filter the first filtered signal, and a second bandwidth and a second flatness of the second filtered signal obtained after filtering are calculated. After the initial filtering of the first filter, a first filtered signal is obtained, and through the calculation of the first bandwidth and the first flatness of the first filtered signal, how the signal is processed after the first filter can be known, so that how to adjust the configuration of the second filter and/or the third filter can be selected. In this embodiment, the second filter is set to have different modes, and it is able to determine which mode the second filter should be adjusted to according to the type of the received signal, where the filtering effect of the second filter on the first filtered signal in different modes is also different, and the mode of the second filter may be adjusted according to a corresponding relationship, that is, a corresponding relationship between the type of the signal and the mode of the second filter. Therefore, in this embodiment, the second filter can determine how to filter the first filtered signal according to the type of the signal, regardless of the first bandwidth and the first flatness of the first filtered signal.
In step 203, a filtering configuration of a third filter is adjusted according to the first bandwidth, the second bandwidth, and the target bandwidth, and the first flatness, the second flatness, and the target flatness, and the third filter is controlled to filter the second filtered signal, so that the third bandwidth and the third flatness of the filtered third filtered signal can meet the preset requirement. After the filtering by the second filter in step 202, the second bandwidth and the second flatness of the obtained second filtered signal, together with the first bandwidth and the first flatness of the first filtered signal calculated in step 201, and the final target bandwidth and the target flatness to be achieved, can be adjusted to make the third bandwidth and the third flatness of the third filtered signal obtained after the filtering by the third filter of the second filtered signal meet the preset requirements. In this embodiment, the configuration of the third filter is dynamically adjustable according to the first bandwidth, the second bandwidth, and the target bandwidth, and the first flatness, the second flatness, and the target flatness.
According to the technical scheme, after the signal is received, the signal is filtered for at least three times, and the subsequent filtering can be dynamically adjusted according to the actual bandwidth and the actual flatness of the signal after the previous times of filtering, so that the received signal can be dynamically filtered for multiple times according to the preset requirement, and the filtered signal can meet the preset requirement, and the signal receiving performance is improved.
In a possible embodiment, the preset requirements are:
A＝A1+A2+A3， (1)
B＝B1+B2+B3， (2)
wherein, a is the target bandwidth, a1 is the first bandwidth, a2 is the second bandwidth, A3 is the third bandwidth, B is the target flatness, B1 is the first flatness, B2 is the second flatness, and B3 is the third flatness.
In one possible embodiment, the first filter is a radio frequency filter, the second filter is an intermediate frequency filter, and the third filter is a baseband filter. For example, the first filter may be a filter of a radio frequency front end, for example, with SAW (surface acoustic wave filter) or BAW (bulk acoustic wave filter), etc.; the second filter may be an intermediate frequency filter inside the RFIC for filtering out in-band signals of the intermediate frequency signal, wherein the intermediate frequency filter may be implemented by a CMOS circuit; the third filter may be a low pass filter internal to the baseband for further removing unwanted signals at the intermediate frequency, which may be, for example, a digital filter.
In this disclosure, the preset number of times may be greater than 3 times, and the types of the filters for filtering the signal, the positions and the number of the filters capable of performing dynamic configuration adjustment, and the manner of adjusting the configuration are not limited as long as the target frequency response flatness can be generated after multiple filtering.
Fig. 3 is a flowchart illustrating still another signal receiving method according to an exemplary embodiment of the present disclosure. As shown in fig. 3, the method includes step 301 in addition to step 101 shown in fig. 1 and steps 201 to 203 shown in fig. 2.
In step 301, the weights occupied by the remaining filtering of each time in the preset number of filtering are adjusted according to the first bandwidth, the expected bandwidth, the target bandwidth, the first flatness, the expected flatness, and the target flatness, so that the bandwidth and the flatness of the signal after the preset number of filtering can meet the preset requirements, the expected bandwidth is an expected value of the first bandwidth, and the expected flatness is an expected value of the first flatness.
In a possible embodiment, in the case that the preset number of times is 3, the preset requirement may be:
A＝A1+a*A2+b*A3， (3)
B＝B1+a*B2+b*B3， (4)
wherein a is the target bandwidth, a1 is the first bandwidth, a2 and A3 are bandwidths of filtered signals respectively obtained after the first filtered signal is filtered by the remaining two times in the preset times, B is the target flatness, B1 is the first flatness, B2 and B3 are flatness of filtered signals respectively obtained after the first filtered signal is filtered by the remaining two times in the preset times, and a and B are weighting factors of the remaining two times, respectively.
The target bandwidth and the target flatness are target values of the bandwidth and flatness that should be achieved after the filtering of step 102 shown in fig. 1, and according to formula (3) and formula (4), after the signal to be filtered is subjected to the first filtering through the first filter, the size of the weighting factors a and b occupied by the remaining two filtering can be adjusted according to the size relationship between the actual bandwidth (first bandwidth) and the actual flatness (first flatness) of the first filtered signal and the expected bandwidth and the expected flatness. For example, if a1, B1 is larger than the expected value, it can be adjusted by decreasing the weighting factor a and/or the weighting factor B, and if a1, B1 is smaller than the expected value, it can be adjusted by increasing the weighting factor a and/or the weighting factor B so that the bandwidth and flatness of the signal after the preset number of filtering can satisfy the preset requirements.
The following sets of actual data are given to illustrate the embodiment:
in the case where the preset number of times is 3, the first bandwidth of the first filtered signal obtained after the signal that needs to be received is filtered by the first filter is 300kHz and the first flatness is 2, whereas the known target bandwidth is 180kHz, the target flatness is 1.2, the expected bandwidth is 200kHz, and the expected flatness is 1.5. In order to satisfy the preset requirements shown in the formula (3) and the formula (4), since the first bandwidth and the first flatness are respectively larger than the target bandwidth and the target flatness, the sizes of a and b need to be adjusted, so that the weights occupied by the remaining two times of filtering in the third filtering are reduced, for example, a may be 0.85, and b may be 0.75. And (3) knowing that the type of the signal to be received is NBIOT, adjusting the mode of the second filter to finally obtain a second bandwidth of the second filtered signal of 180kHZ and a second flatness of 1.4, and finally adjusting the configuration of the third filter according to the obtained first bandwidth, first flatness, second bandwidth, second flatness, weight factor a and weight factor b, so that the third bandwidth and third flatness of the third filtered signal obtained after being filtered by the third filter can meet the preset requirements shown in formula (3) and formula (4).
In this embodiment, the preset number of times may also be greater than 3 times, and no matter how many times the preset number of times is, the weight of the remaining multiple filtering in the filtering of the preset number of times is calculated according to the magnitude relationship between the first bandwidth and the first flatness of the first filtering signal and the expected value thereof, for example, when the preset number of times is 4 times, the preset requirement may also be:
A＝A1+a*A2+b*A3+c*A4， (5)
B＝B1+a*B2+b*B3+c*B4， (6)
wherein a is the target bandwidth, a1 is the first bandwidth, a2, A3, and a4 are bandwidths of filtered signals respectively obtained after the first filtered signal is subjected to remaining three-time filtering in the preset number of times, B is the target flatness, B1 is the first flatness, B2, B3, and B4 are flatness of filtered signals respectively obtained after the first filtered signal is subjected to remaining three-time filtering in the preset number of times, and ab and c are weight factors of the remaining three-time filtering, respectively.
After controlling the first filter to filter the signal, adjusting the remaining two or more times of filtering in the preset times so that the bandwidth and the flatness of the signal after the filtering in the preset times can meet the preset requirements, where the adjusting may be adjusting the mode and/or configuration of the filter used in the remaining two or more times of filtering as shown in step 202 and step 203, or adjusting the weight of the remaining two or more times of filtering in the preset times, or simultaneously adjusting the two or more times of filtering so as to meet the final filtering requirement, thereby improving the performance of signal reception.
