Abstract

The invention discloses a method for determining a self-adaptive anti-interference detection threshold of a high-dynamic digital receiver. The method is realized through an A / D data cache module, a windowing processing module, a time-frequency conversion module and a detection threshold determination module. The A / D data caching module is used for caching the A / D acquisition data of the received signals; the windowing processing module performs windowing processing on the cache data; the time-frequency conversion module performs time-frequency conversion on the windowed data; and the detectionthreshold determination module determines the self-adaptive anti-interference detection threshold. The problem that a traditional anti-interference detection threshold determination method is poor inadaptability is solved.

Description

technical field [0001] The invention relates to the technical field of determining an anti-interference detection threshold, in particular to a system and method for determining an adaptive anti-interference detection threshold for a high dynamic digital receiver. Background technique [0002] High-dynamic digital receivers need to digitally process the received signal to restore the original information. When the power of the narrow-band interference signal is much greater than the power of the normal signal, it is difficult to achieve good results by only relying on the processing gain of the system to suppress the narrow-band interference. Therefore, it is necessary to use an anti-interference method to suppress narrow-band interference, and the determination of the anti-interference detection threshold directly affects the anti-interference ability of the digital receiver. The traditional determination method of anti-interference detection threshold adopts the method of ...
