Problems solved by technology

However, in the superheterodyne receiving scheme, as the useful signal amplitude increases, the adjacent channel selectivity deteriorates more seriously
When working in the repeater, the power of the hand station can easily make the signal amplitude enter the strong signal range, which will seriously affect the customer's call quality and experience
In the prior art, the above-mentioned technical problems will be solved by modifying the PCB to increase circuit design, adding devices, etc., but this will increase the investment in hardware costs to a certain extent, which is not suitable for mass production, so a method that does not increase hardware costs is required. Invest in and be able to solve the above technical problems

Abstract

The invention discloses a method for improving adjacent channel selectivity. The method comprises the following steps: acquiring a first parameter of a current receiving signal of a receiver; the first parameter comprises signal strength or signal power; judging whether the first parameter is greater than a first threshold value or not, wherein the first threshold value is set corresponding to the first parameter; and if yes, determining a target gain value according to the first parameter, and adjusting the gain of a programmable gain amplifier of the communication device to the target gain value. According to the technical scheme provided by the invention, the adjacent channel selectivity of the receiver can be improved on the premise that the hardware cost input is not increased. The invention further provides a communication device and a computer readable storage medium.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method and related apparatus for improving the selectivity of adjacent channels. Background technique [0002] In walkie-talkie communication, the transmitter is the transmitter and the receiver is the receiver. Both the transmitter and the receiver have their rated operating frequency bands. However, in the superheterodyne receiving scheme, with the increase of the useful signal amplitude, the adjacent channel selectivity deteriorates more seriously. When the repeater is working, the power of the mobile station can easily make the signal amplitude enter the strong signal range, which will seriously affect the customer's call quality and experience. In the prior art, the above-mentioned technical problems are mostly solved by modifying the PCB to increase the circuit design, adding devices, etc., but this will increase the hardware cost to a certain ext...
