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.
In a communication system, the receive chain is broadly divided into a radio frequency part and a baseband part. The radio frequency part mainly completes the functions of frequency spectrum shifting and signal amplification, and the baseband part mainly completes the functions of demodulation and decoding. Among the performance indicators of the receiving link, sensitivity is an important performance indicator. In the unmanned aerial vehicle image transmission communication system, the image transmission distance is directly influenced by the sensitivity. Therefore, referring to fig. 1, in order to improve the sensitivity of the receiving link, a first-stage low noise amplifier is usually added at the front end of the radio frequency in the prior art, so that the noise coefficient of the receiving link can be effectively reduced, the sensitivity performance is improved, and thus the image transmission distance is increased.
However, the addition of the low noise amplifier may reduce the dynamic range of the input signal of the receiving link, and under the condition of large input signal power or large signal interference, the radio frequency front end of the image transmission communication system is easily saturated, so that the signal passing through the low noise amplifier cannot be linearly amplified, thereby affecting the short-distance image transmission performance and the anti-interference performance of the image transmission communication system.
In order to solve the above problems, the present disclosure provides a communication control method, apparatus, storage medium, and baseband chip, so as to turn off a low noise amplifier of an image-wise communication system when an input signal is strong, or turn on the low noise amplifier of the image-wise communication system when the input signal is weak, thereby avoiding that a short-distance image-wise performance and an anti-interference performance of the image-wise communication system are affected under a condition of a large input signal power or large signal interference.
Fig. 2 is a flowchart illustrating a communication control method according to an exemplary embodiment of the present disclosure, and referring to fig. 2, the communication control method may be applied to a baseband chip of a legacy communication system, and includes:
in step S201, a target gain value required by a receiving link of the map communication is determined.
When the input signal is weak, the receiving link needs a larger gain value to control the input signal, and when the input signal is strong, the receiving link needs a smaller gain value to control the input signal. Therefore, in the embodiment of the present disclosure, the strength of the input signal can be determined by determining the target gain value required by the receiving link of the mapping communication, so as to perform different communication control on the input signal.
In one possible approach, the determining the target gain value required by the receiving link may be to determine an input signal strength value and a target signal strength value of the receiving link, and then determine the target gain value required by the receiving link according to the input signal strength value and the target signal strength value.
For example, the target signal strength value is used to represent a signal strength value corresponding to the optimal communication index of the map-based communication system, and may be preset according to an actual communication requirement, and different map-based communication systems may correspond to different target signal strength values.
For example, an input Signal Strength Indicator (RSSI) of the receiving link may be calculated in real time according to current communication parameters during each graph-transmitted communication process, and then a target gain value required by the receiving link may be determined in real time according to the calculated RSSI and target RSSI. For example, the input signal strength of the receiving link of the mapping communication system is-10 dBm, and the target signal strength value of the receiving link is 0dBm, in which case, the input signal strength value can be made to be consistent with the target signal strength value by a gain value of 10dBm, so that the gain value of 10dBm can be added to the reference gain value of the mapping communication system to obtain the target gain value required by the receiving link, for example, the reference gain value is 50dBm, and then the target gain value required by the receiving link can be determined to be 60 dB.
It should be understood that the input signal strength value may be represented by the amplitude of the input signal, and thus, in the embodiments of the present disclosure, may be represented by calculating the amplitude of the input signal of the receiving chain, and determining the target gain value of the receiving chain according to the input signal amplitude and the target input signal amplitude.
Step S202, when the target gain value is smaller than a first preset threshold value, closing a low noise amplifier of the image transmission communication system, and controlling a gain value of a radio frequency module of the image transmission communication system to increase a preset gain value.
For example, the first preset threshold may be preset according to a dynamic range of a target gain value of the receiving link and actual requirements, for example, the dynamic range of the target gain value of the receiving link is 10dB to 100dB, and in order to avoid performance loss caused by frequent turning off or on of the low noise amplifier, the first preset threshold may be set to any value between 30dB and 40dB, and so on, and the process of setting the first preset threshold is not limited in the embodiments of the present disclosure.
For example, the preset gain value may be determined according to a signal gain value corresponding to the low noise amplifier. For example, if the target gain value of the low noise amplifier is 10dB, the preset gain value may be set to 10 dB.
When the target gain value is smaller than the first preset threshold value, the power of the input signal is large, which may cause a saturation phenomenon at the radio frequency front end of the graph-based communication system, so that the signal passing through the low noise amplifier cannot be linearly amplified, thereby affecting the short-range graph transmission performance and the anti-interference performance of the graph-based communication system.
In addition, in the process of turning off the low noise amplifier, the target gain value of the receiving link is suddenly reduced, which may cause the signal to noise ratio and the demodulation performance of the receiving link to be affected. That is to say, the embodiment of the present disclosure may compensate the gain value of the receiving link, which is decreased due to the low noise amplifier being turned off, by increasing the gain value of the radio frequency module, thereby avoiding sudden change of the total gain value of the receiving link before and after the low noise amplifier is turned off, and ensuring stability of the image transmission communication.
Step S203, when the target gain value is greater than a second preset threshold, turning on the low noise amplifier, and controlling the gain value of the radio frequency receiving module to decrease the preset gain value.
For example, the second preset threshold may be preset according to a dynamic range of the target gain value of the receiving link and actual requirements, for example, the dynamic range of the target gain value of the receiving link is 10dB to 100dB, and in order to avoid performance loss caused by frequent turning off or on of the low noise amplifier, the second preset threshold may be set to any value between 70dB and 80dB, and so on, and the embodiment of the present disclosure does not limit the setting process of the second preset threshold.
When the input signal power is small, in order to improve the sensitivity of the input signal, a low noise amplifier of the image communication system can be turned on. In addition, in the process of turning on the low noise amplifier, the target gain value of the receiving link is suddenly increased, so that the signal to noise ratio and the demodulation performance of the receiving link are affected. That is to say, the embodiment of the present disclosure can offset the gain value of the receiving link increased due to the low noise amplifier being turned on by reducing the gain value of the radio frequency module, thereby avoiding sudden change of the total gain value of the receiving link before and after the low noise amplifier is turned on, and ensuring the stability of the image transmission communication.
In a possible manner, in order to further avoid performance loss caused by frequent turning off or turning on of the low noise amplifier, when the target gain value is between a first preset threshold and a second preset threshold, a historical state of the low noise amplifier in a last communication cycle may be determined, and if the historical state is an on state, the low noise amplifier is turned on, and if the historical state is an off state, the low noise amplifier is turned off.
For example, the first preset threshold is 30dB, the second preset threshold is 70dB, and the target gain value is 50dB, that is, the target gain value is between the first preset threshold and the second preset threshold, in this case, the history state of the low noise amplifier in the last communication cycle can be determined. If it is determined that the history state of the low noise amplifier in the last communication cycle is the on state, the low noise amplifier is turned on, but if the history state is the off state, the low noise amplifier is turned off.
It should be noted that, since the low noise amplifier is in the off state at the time of initial gain calibration in the image communication system, the image communication system defaults the initial state of the low noise amplifier to the off state, and thus, if it is determined in the first determination that the target gain value is between the first preset threshold and the second threshold, the low noise amplifier may be kept in the off state.
Through the mode, when the target gain value is between the first preset threshold and the second preset threshold, the state of the low noise amplifier of the previous communication period can be judged, and the state of the low noise amplifier is kept unchanged, so that performance loss caused by frequent turning-off or turning-on of the low noise amplifier can be avoided.
In one possible approach, the low noise amplifier may have a bypass function, and accordingly, turning off the low noise amplifier of the wireless communication system may be turning off the low noise amplifier by enabling the bypass function of the low noise amplifier, and simultaneously, turning on the low noise amplifier may be turning on the low noise amplifier by not enabling the bypass function of the low noise amplifier.
In the embodiment of the present disclosure, the graph communication system may employ a low noise amplifier having a bypass (bypass) function in hardware. Referring to fig. 3, the bypass function corresponds to having a switch at both ends of the low noise amplifier, and closing the switch enables the bypass function of the low noise amplifier, that is, the target gain value of the low noise amplifier is 0. Conversely, turning off the switch does not enable the bypass function of the lna, i.e. the target gain value of the lna is the gain value corresponding to the lna, e.g. the gain value corresponding to the lna is 10dB, in which case the target gain value of the lna is 10 dB.
It should be understood that the switch in fig. 3 is shown for convenience of explaining the bypass function of the low noise amplifier, and is not used to indicate the actual connection relationship of the communication system, and thus the switch in fig. 3 is connected to other modules by a dotted line.
By the mode, the low-noise amplifier with the bypass function can be adopted on hardware, the low-noise amplifier is turned off by enabling the bypass function, or the low-noise amplifier is turned on by not enabling the bypass function, and the control is simple, so that the stability of image transmission communication can be guaranteed more efficiently.
The communication control method of the present disclosure is explained below by another exemplary embodiment.
Referring to fig. 4, the communication control method may be applied to a baseband chip of a legacy communication system, and may include the steps of:
step S401 determines the input signal strength value RSSI and the target signal strength value of the receiving link.
Step S402, determining a target gain value required by the receiving link according to the input signal strength value RSSI and the target signal strength value.
And step S403, judging whether the target gain value is smaller than a first preset threshold value, if so, entering step S404, otherwise, entering step S405.
Step S404, turning off the low noise amplifier by enabling the bypass function of the low noise amplifier, and controlling the gain value of the radio frequency module to increase the preset gain value.
Step S405, judging whether the target gain value is larger than a second preset threshold value, if so, entering step S406, otherwise, entering step S407.
Step S406, turning on the low noise amplifier by disabling the bypass function of the low noise amplifier, and controlling the gain value of the radio frequency module to decrease the preset gain value.
Step S407, determining whether the history state of the low noise amplifier in the last communication cycle is an on state, if yes, going to step S406, otherwise going to step S404.
By the communication control method, the short-distance image transmission performance and the anti-interference performance of the image transmission communication system can be prevented from being influenced under the condition of large input signal power or large signal interference. And moreover, sudden change of the total gain value of the receiving link in the process of starting or closing the low-noise amplifier can be avoided, so that the total gain value of the receiving link is in smooth transition before and after the low-noise amplifier is started or closed, and the stability of image transmission communication is ensured.
