Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of 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 apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The technical scheme provided by the embodiment of the application is described in detail through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Example 1
Fig. 1 is a flowchart of an uplink gain adjustment method according to an embodiment of the present application. As shown in fig. 1, the method specifically comprises the following steps: the process comprises the following steps:
step S101, coupling signals of an uplink are obtained through a coupler;
the coupler is connected to the output end of the low noise amplifier, and couples the signal amplified by the uplink to the detection circuit. It will be appreciated that the coupled signal may be of the same signal characteristics as the signal output by the power amplifier.
Step S102, performing power detection on the coupling signal by adopting a detection circuit to obtain peak power or average power of the coupling signal;
the peak detection circuit is used for detecting the peak power of an input radio frequency signal; the root mean square detection circuit is used for detecting the average power of the input radio frequency signal.
Fig. 2 is a schematic circuit connection diagram of uplink gain adjustment according to an embodiment of the present application. As shown in fig. 2, wherein a low noise amplifier is used to amplify the signal on the receive link. With bypass (bypass) functionality. When the signal strength is too high, the low noise amplifier can be bypassed, thereby reducing the link gain and improving the 1dB compression point of the link.
A coupler for coupling the signal amplified by the uplink and providing the signal to the peak detection circuit and the root mean square detection circuit; the detection circuit comprises a peak detection circuit and a root mean square detection circuit. The peak detection circuit is used for detecting the peak power of an input radio frequency signal; the root mean square detection circuit is used for detecting the average power of the input radio frequency signal. And the analog-to-digital conversion module is used for converting the analog signals into digital signals and inputting the digital signals into the FPGA. And the FPGA module is used for receiving and processing the data received by the uplink. The signal intensity of the uplink receiving link is judged by analyzing and processing the voltage of the detection circuit, and then the signal intensity of the uplink is controlled by controlling the low noise amplifier and the program-controlled attenuator.
Step S103, generating a gain adjustment instruction when the peak power exceeds a first threshold or the average power exceeds a second threshold;
in the scheme, one of the conditions is met, or the gain adjusting instruction is generated under the condition that both conditions are met, and the scheme is not excessively limited.
In one embodiment, the detection circuit includes a peak detection circuit and a root mean square detection circuit;
the peak detection circuit and the root mean square detection circuit are connected to the coupler through a switch.
As can be seen from the above circuit connection schematic diagram, the coupling signal obtained by the coupler can be directly transmitted to the detection circuit. And the peak power and the average power are detected by two detection units in the detection circuit, namely a peak detection circuit and a root mean square detection circuit respectively. It can be understood that the peak detection circuit and the root mean square detection circuit can both output voltage value data, and further obtain the power value corresponding to the voltage value data through a conversion formula.
The scheme can simplify the circuit design through the design, and has no influence of excessive circuit devices in the signal transmission process, so that the obtained measurement result is more accurate.
In one embodiment, the switch is configured to control the peak detection circuit to be switched on, or to control the root mean square detection circuit to be switched on, or to control the peak detection circuit and the root mean square detection circuit to be switched on simultaneously.
It will be appreciated that when the peak detection circuit is accessed, a gain adjustment instruction may be generated if the peak power exceeds a first threshold; when the root mean square detection circuit is accessed, a gain adjustment instruction can be generated under the condition that the average power exceeds a second threshold value; when the peak detection circuit and the root mean square detection circuit are simultaneously connected, the gain adjustment instruction may be generated when the peak power exceeds a first threshold or when the average power exceeds a second threshold.
The scheme can be adjusted according to actual demands based on convenient operation of the switch through the arrangement, and the simplicity and the use flexibility of the structure in the circuit provided by the scheme are improved.
Step S104, the gain adjustment instruction is sent to the program controlled attenuator connected in the uplink so as to control the program controlled attenuator to perform step adjustment.
Wherein, the program-controlled attenuator is an electronic device for adjusting the attenuation degree by changing the signal intensity. It is commonly used in the fields of broadcasting, television, communication, etc., and can help control the quality of signal transmission. In the broadcast and television fields, program-controlled attenuators can adjust the signal strength of a television channel to achieve optimal reception quality. In the field of communications, it may be used to adjust the attenuation level of a signal in a network to ensure stability and reliability of the signal during transmission.
The main principle of a programmable attenuator is to use a variable resistor to adjust the strength of the signal. It is typically controlled by a microprocessor which contains a variable resistor network and a digital controller. When the signal passes through the program-controlled attenuator, the digital controller receives a command, and then controls the resistance value of the variable resistor, so as to adjust the signal strength to achieve the required attenuation degree.
Program controlled attenuators are very widely used in communication systems. For example, in the field of mobile communications, programmable attenuators may be used to adjust base station signal strength to achieve optimal coverage and capacity of a wireless network. In the satellite communication field, programmable attenuators can be used to adjust signal attenuation to ensure that signals on the satellite remain stable and reliable during transmission.
The step adjustment may be to identify the peak power and the average power again after performing the adjustment once, and determine whether to trigger the next adjustment after identifying the corresponding result. The amplitude of each adjustment may be a preset decay step. For example 0.05dB, or 0.1dB, etc.
According to the technical scheme provided by the embodiment, the coupling signal of the uplink is obtained through the coupler; performing power detection on the coupling signal by adopting a detection circuit to obtain peak power or average power of the coupling signal; generating a gain adjustment instruction when the peak power exceeds a first threshold or the average power exceeds a second threshold; and sending the gain adjustment instruction to a program controlled attenuator connected in the uplink so as to control the program controlled attenuator to perform step adjustment. The scheme can detect whether a strong interference signal exists in an uplink by using peak detection and root mean square detection, so that the uplink gain is controlled, and the quality of a received signal is ensured.
In one embodiment, the gain adjustment instruction is sent to a program-controlled attenuator connected in the uplink, so as to control the program-controlled attenuator to increase a preset attenuation step length from the current attenuation intensity, and obtain the increased attenuation intensity;
and acquiring an uplink coupling signal through a coupler again, and performing power detection on the coupling signal, and if the peak power exceeds a first threshold or the average power exceeds a second threshold, generating a gain adjustment instruction again to control the program-controlled attenuator to increase a preset attenuation step length until the peak power does not exceed the first threshold and the average power does not exceed the second threshold, and ending.
After the adjustment is performed once, whether the peak power or the average power still exceeds the threshold value can be identified, and if so, a gain adjustment instruction is generated again to control the program-controlled attenuator to increase a preset attenuation step length until the peak power does not exceed the first threshold value and the average power does not exceed the second threshold value.
The scheme can ensure the accuracy and the real-time performance of adjustment and the quality of uplink signals through the cyclic setting.
Example two
Fig. 3 is a flowchart of an uplink gain adjustment method according to a second embodiment of the present application. As shown in fig. 3, the method specifically comprises the following steps:
step S301, a coupling signal of an uplink is obtained through a coupler;
step S302, performing power detection on the coupling signal by adopting a detection circuit to obtain peak power or average power of the coupling signal;
step S303, performing power detection on the coupling signal by adopting a detection circuit to obtain peak power or average power of the coupling signal;
step S304, the gain adjustment instruction is sent to the program controlled attenuator connected in the uplink so as to control the program controlled attenuator to perform step adjustment.
Step S305, identifying whether the current attenuation intensity of the program-controlled attenuator reaches a preset intensity value;
each time the detector circuit exceeds a threshold, its uplink gain needs to be adjusted downward (gain reduction) by a step of XdB. When the attenuation setting of the program-controlled attenuator is smaller, the program-controlled attenuator is firstly adjusted to increase the attenuation of the program-controlled attenuator by XdB.
Step S306, if so, sending the gain adjustment instruction to the low noise amplifier connected in the uplink, so that the low noise amplifier triggers a bypass function.
And when the attenuation value of the program-controlled attenuator exceeds the preset intensity value, bypassing the low-noise amplifier.
Wherein the bypass function may be that the low noise amplifier does not amplify the received signal, and passes directly, as this function the signal may bypass the low noise amplifier directly, thereby reducing the gain.
By means of the arrangement, other modes except uplink gain adjustment for the program-controlled attenuator can be provided, and the situation that the scheme cannot cope with received signals with larger attenuation requirements due to the control range of the program-controlled attenuator can be avoided.
In one embodiment, after sending the gain adjustment instruction to a low noise amplifier connected in the uplink to cause the low noise amplifier to trigger a bypass function, the method further comprises:
acquiring a gain difference value of the low noise amplifier trigger bypass function and the non-trigger bypass function;
and controlling the gain adjustment amplitude of the program-controlled attenuator according to the gain difference value.
In order to achieve the effect that gain adjustment is performed according to a certain step length in each adjustment, the scheme provides a scheme for controlling a program-controlled attenuator according to gain difference values caused by a bypass function. For example, the step length of the program-controlled attenuator is 0.1dB, and the gain difference caused by the bypass function is 0.5dB, so that the program-controlled attenuator can be adjusted from the current inhibition intensity of 0.6dB to the inhibition intensity of 0.2dB while triggering the bypass function in the current adjustment process. Thus, the magnitude of this adjustment is still 0.1dB throughout the uplink.
By means of the arrangement, the embodiment can ensure that the adjustment process is gradual, and the influence on the quality of the received signal caused by overlarge adjustment amplitude at one time due to triggering of the bypass function is avoided.
In one embodiment, controlling the gain adjustment amplitude of the programmable attenuator according to the gain difference value includes:
the gain adjustment amplitude is determined using the following equation:
X′dB＝(X-G delta )dB；
wherein X' dB is gain adjustment amplitude, G delta And X is a preset attenuation step length of the program-controlled attenuator.
When the attenuation value of the program-controlled attenuator exceeds a certain range, the low noise amplifier is bypassed, and the program-controlled attenuator is properly adjusted so that the uplink attenuation is still increased by XdB. (e.g., if the gain difference between the bypass and non-bypass of the low noise amplifier is G delta The programmable attenuator needs to be adjusted (X-G when the low noise amplifier bypasses delta )dB)。
By such arrangement, the scheme can ensure the accuracy of uplink gain adjustment.
