Abstract

The invention discloses an interference detection and suppression optimization method. The method comprises the steps of frequency domain transformation, interference detection, interference suppression and time domain transformation. Background noise estimation and self-adaptive determination of an interference detection threshold are carried out on the converted frequency domain digital signal in the interference detection, so that the detection accuracy of the interference signal is improved, and the reduction of signal-to-noise ratio loss possibly caused by interference suppression due toinaccurate detection threshold setting is facilitated. The method is high in universality, and is particularly suitable for interference signal detection in direct sequence spread spectrum communication.

Description

technical field [0001] The invention relates to the technical field of communication signal processing, in particular to an interference detection and suppression optimization method for interference signals. Background technique [0002] In radio communications such as satellite communications and mobile communications, communication signals are often mixed with various interference signals when they are received by the receiving end. The detection and elimination of these interference signals is conducive to the correct reception of communication signals. [0003] In the prior art, it is difficult to optimize the interference detection because the background noise cannot be accurately estimated and the interference detection threshold is fixed. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide an interference detection and suppression optimization method to solve the problem of inaccurate background noise estima...
