Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The present application provides a signal receiving method, which may be applied to ad hoc network devices included in all wireless ad hoc network communication systems, and the following embodiments will describe the signal receiving method provided in the present application in detail.
Referring to fig. 1, a schematic flow chart of a signal receiving method provided in the embodiment of the present application is shown, where the signal receiving method may include:
step S101 of receiving, as a target radio signal, a radio signal matched to an antenna from among radio signals from the air via a single antenna.
The target radio signal comprises at least one radio signal.
Specifically, radio signals (i.e., electromagnetic waves) of a spatial electromagnetic field are divided into a plurality of frequency bands, and in the field of radio communications, signals in a specific frequency band need to be selected for preferential locking.
In this step, when a radio signal of the spatial electromagnetic field is transmitted to an ad hoc network device in the wireless ad hoc network communication system, the ad hoc network device may receive a radio signal matched with the antenna from the radio signal from the air interface through a single antenna installed in itself.
Alternatively, the process of receiving the radio signal matched with the antenna from the radio signal from the air interface through the single antenna in the step "may include: radio signals within the operating frequency range of the antenna are received from the radio signals from the air interface by a single antenna.
That is, the "matching" refers to a radio signal located in the operating frequency range of the antenna, for example, if the operating frequency range of the antenna in this step is 350M to 400M, the step can receive a radio signal in the range of 350M to 400M.
For convenience of the subsequent description, this step defines the received radio signal as a target radio signal. Since the antenna can receive radio signals within a certain frequency range, the target radio signals received in this step include at least one radio signal, and optionally, one radio signal may refer to a radio signal of one frequency point.
Step S102, selecting one path of radio signal with the quality greater than or equal to a preset receiving quality threshold from the target radio signal, and receiving and forwarding the target radio signal on a channel where the selected radio signal is located.
Here, the preset reception quality threshold refers to a reception sensitivity of the wireless ad hoc network device, where the reception sensitivity can reflect a reception capability of the ad hoc network device (used as a receiver) for a weak signal under a specified bandwidth, and when a radio signal quality is lower than the reception sensitivity (i.e., the reception quality threshold), a situation that the receiver cannot demodulate the radio signal may occur.
Therefore, this step needs to select one path of radio signal with quality higher than the receiving quality threshold from the target radio signal, and perform service receiving and forwarding of the normal sensitivity service on the channel where the selected path of radio signal is located.
It should be noted that, in this step, one radio signal is selected from the target radio signal, the antenna path may be divided into multiple signal paths (at this time, the system receiving sensitivity may decrease, for example, if the antenna path is divided into two signal paths, the system receiving sensitivity may decrease by 3dB), based on which, after one radio signal is selected in this step (that is, the optimization stage is ended), multiple signal paths need to be combined into one path (after the multiple signal paths are combined into one path, the system receiving sensitivity may be improved compared with the case of being divided into multiple paths, for example, after two signal paths are combined into one path, the system receiving sensitivity may be improved by 3dB), so as to receive and forward the service with normal sensitivity on the channel where the selected radio signal is located.
In addition, it should be noted that the "target radio signal" in the step of "receiving and forwarding the target radio signal on the channel where the selected radio signal is located" may be different from the target radio signal in the step of "selecting one radio signal whose quality is greater than or equal to the preset receiving quality threshold from the target radio signal", because the service receiving and forwarding process needs to be performed at multiple times, and the step only needs to select one radio signal from the target radio signals received at a certain time.
The signal receiving method comprises the steps of firstly receiving matched radio signals from an air interface through a single antenna to serve as target radio signals, then selecting one path of radio signals with the quality larger than or equal to a preset receiving quality threshold from the target radio signals, and receiving and forwarding the target radio signals on a channel where the selected radio signals are located. Because the signal receiving method provided by the application can realize the receiving and forwarding of the target radio signal by only one antenna, compared with the prior art which needs a plurality of antennas, the application improves the utilization rate of the ad hoc network equipment and reduces the hardware cost.
Moreover, when the target radio signals comprise one or more radio signals at different service stages, the method and the device can self-adaptively and dynamically adjust the enabling of the receiving path of the wireless ad hoc network communication system, so that the normal service can be received and forwarded on the preferred receiving path, the receiving and processing performance of the system is greatly improved, and the overall working efficiency is improved.
An optional embodiment of the present application is described below, which describes in detail the process of "step S102, selecting one radio signal with quality greater than or equal to the preset receiving quality threshold from the target radio signal" in the above description.
As described in the foregoing embodiment, the target radio signal includes at least one radio signal, in this embodiment, it may be first determined whether the target radio signal is a one-way radio signal, and if the target radio signal is the one-way radio signal, that is, the target radio signal includes only one radio signal, this embodiment may determine whether the quality of the target radio signal is greater than or equal to a reception quality threshold, and if so, the target radio signal is used as the one-way radio signal selected in this embodiment.
If the target radio signal is not a single-channel radio signal, that is, the target radio signal includes multiple radio signals, the process of this embodiment may include: dividing the target radio signal into a plurality of radio signals according to a preset frequency point, and selecting one radio signal with the quality greater than or equal to a receiving quality threshold from the plurality of radio signals.
Here, the preset frequency points are frequency points within the operating frequency range of the single antenna mentioned in the above embodiment.
Specifically, it has been introduced that each path of radio signals included in the target radio signal may be radio signals of one frequency point, and then some frequency points may be preset in this embodiment, and subsequently, signal reception and forwarding may be performed on a channel corresponding to the preset frequency points.
It should be noted that the dividing provided in this embodiment may specifically be to screen out a radio signal corresponding to a preset frequency point from a target radio signal, that is, optionally, the process of "dividing the target radio signal into a plurality of radio signals according to the preset frequency point" includes: and screening radio signals respectively corresponding to a plurality of frequency points contained in the preset frequency points from the target radio signals, and taking the radio signals respectively corresponding to the screened frequency points as a plurality of paths of radio signals.
In this embodiment, the number of preset frequency points is the same as the number of channels of the screened radio signals.
For example, the first frequency point and the second frequency point may be preset in this embodiment, for example, referring to the schematic process of dividing the target radio signal into two radio signals shown in fig. 2a, and the schematic process of selecting one radio signal from the two radio signals shown in fig. 2b, the first frequency point corresponding to the F1 channel and the second frequency point corresponding to the F2 channel are preset. After the first frequency point and the second frequency point are preset, in this embodiment, radio signals corresponding to the first frequency point and the second frequency point respectively can be screened from the target radio signal, the radio signal corresponding to the screened first frequency point is used as the first path of radio signal, and the radio signal corresponding to the screened second frequency point is used as the second path of radio signal.
Optionally, when "one radio signal with quality greater than or equal to the reception quality threshold is selected from the several radio signals", any one radio signal with quality greater than or equal to the reception quality threshold may be selected from the several radio signals.
When any radio signal is selected, if the quality of the channel where the selected radio signal is located is poor, the quality of the received and forwarded signal may be poor, thereby affecting the receiving processing performance of the system. Therefore, in a preferable case, the embodiment may select one radio signal with the best quality from the radio signals whose quality meets the receiving quality threshold, that is, the process of "selecting one radio signal whose quality is greater than or equal to the receiving quality threshold from the several radio signals" may include:
step a1, determining the radio signal with the quality greater than or equal to the receiving quality threshold from the plurality of radio signals as the radio signal to be screened.
In this step, the radio signals that can be demodulated by the receiver may be first screened out from the plurality of radio signals, and the screened out radio signals are defined as the radio signals to be screened out.
Step a2, selecting one path of radio signal with the best quality from the radio signals to be screened.
For example, referring to fig. 2b, if the quality of the F1 channel is better than the quality of the F2 signal, the F1 signal may be selected in this step.
It should be noted that, the processes of steps a1 and a2 are only examples, and are not limited to the present application, for example, this embodiment may also select one radio signal with the best quality from the several radio signals, then determine whether the quality of the radio signal is greater than or equal to the reception quality threshold, if so, use the radio signal as the selected radio signal, otherwise, select one radio signal with the second best quality from the several radio signals, and repeat the determination and selection process until the best radio signal of the radio signals with the quality greater than or equal to the reception quality threshold is selected as the selected radio signal.
In summary, the present embodiment comprehensively considers the requirement characteristics of different phases of the service, when only one radio signal is received, if the quality of the radio signal is greater than or equal to the reception quality threshold, the normal sensitivity service is subsequently received and forwarded on the channel where the radio signal is located, and when multiple radio signals are received, one radio signal can be preferentially selected from the multiple radio signals, so that the normal sensitivity service is subsequently received and forwarded on the channel where the radio signal is located. Therefore, the method and the device can adaptively and dynamically adjust the enabling of the receiving channel of the system to realize the service scanning and the selection without service loss and the normal receiving processing after the selection.
Moreover, the embodiment can also implement service receiving and forwarding based on a single antenna, which makes full use of the hardware processing characteristics of the device, and in the service scanning optimization locking period and the normal service receiving and forwarding period, according to the requirement characteristics of different service stages (the target radio signal may include only one radio signal and may also include multiple radio signals in different service stages) of the service, the enabling of the system receiving channel can be adaptively and dynamically adjusted, so that the service scanning optimization without service loss and the normal receiving processing after the optimization are implemented, the hardware multiplexing is implemented, the requirements of different service stages are met, the receiving processing performance of the system is greatly improved, and the overall working efficiency of the system is improved.
