IMPULSIVE NOISE SUPPRESSION PROCEDURE FOR DIVERSITY OF POLARIZATIONS, FOR COMMUNICATION SYSTEMS BY RADIOELECTRIC WAVES.

摘要

Procedure for suppressing impulse noise due to a variety of polarizations, for radio wave communication systems, in which the transmitted signal has a determined polarization and the orthogonal polarization to it does not carry any information signal. It aims to improve the quality of radio communications, in the presence of impulsive noise. With main application in digital radio and digital terrestrial television. It consists of demodulating both the polarization where the information signal is transmitted, and the orthogonal polarization to it, which will act as a monitoring polarization. So when the amplitude of the signal in the monitoring polarization exceeds a certain threshold, it will be assumed that it is a peak of impulsive noise and the portion of the affected information signal will be replaced by zeros. The impulse noise detection can be done in analog or digital way.
