A signal processing method and related device

Abstract

This embodiment provides a signal processing method and a related device. By separating the frequency points of the input signal, several single-frequency point signals are obtained, so that the center of a target single-frequency point signal among the several single-frequency point signals The first signal of the frequency generates a control signal, triggers the frequency point channel corresponding to the target single frequency point signal to output the target single frequency point signal, and then selects the target single frequency point signal from several single frequency point signals , so that the target single frequency point signal is isolated from other single frequency point signals that interfere with the target single frequency point signal, and then the target single frequency point signal is eliminated before processing the target single frequency point signal. The interaction of interference signals suppresses the interference of interference signals on the target single-frequency point signal, solves the problem that the signal anti-interference processing effect is limited by the interference environment simply and at low cost, and further improves the anti-interference performance.

Description

technical field [0001] The present application relates to the field of signal processing, in particular to a signal processing method and related devices. Background technique [0002] At present, users' transmission requirements for large amounts of data and information can be met by setting a large number of channels, increasing channel capacity, or optimizing channel coding methods. However, when a large number of channels are set, the interference between signals will inevitably be aggravated. [0003] At present, there are mainly two technologies to solve the interference between signals. One technology is to set up a traditional tuner (CanTuner), which uses the advantages of high linearity of Can Tuner to improve the anti-interference ability of Can Tuner as much as possible, thereby improving signal transmission. quality. However, setting up the Can Tuner requires a high cost to achieve the anti-jamming effect, and it is difficult to overcome the interference of vari...

Problems solved by technology

However, setting up Can Tuner requires high cost to achieve the anti-interference effect, and it is difficult to overcome the interference of various interference signals on the target signal only through Can Tuner, which limits the application range of this anti-interference technology

Another technique is to use a demodulator to process signals in the subsequent process, and carry out a large amount of complex information processing for different signals through different demodulation methods. Systems in different interference environments require a large number of environmental parameter collection and verification in the early stage, which further increases the difficulty of solving the problem of anti-interference, and the frequency bandwidth and the number of channels will also cause the combination of multiple signals to produce three beat distortion and combination The problem of secondary beat distortion makes the anti-interference ability limited
