Démodulation cohérente par analyse multi-résolution en présence de bruit parasite coloré et gaussien

Abstract : This paper describes a digital communication processing, involving multi-resolution transform and whose effectiveness is studie d if the signal is corrupted either by additive gaussian white noise or by additive gaussian colored noise. When the transmission is corrupted by gaussian white noise, the performances are similar to those obtained by classical data transmission system. The system is evaluated in a presence of colored additive noise whose spectral density has no particular properties, and compared with a technique using Karhunen-Loeve expansion. We also present experimental results which show the validity of the proposed processing, for transmission in ideal channel .
