Abstract :
Tacking into account the ad-hoc and time-variant nature of orthogonal modulation communication systems, the blind techniques are preferred for message estimation. The aim of this paper is to prove that the denoising, one of the most important applications of wavelets theory, can be used as blind estimation method in orthogonal modulation communication systems. The architecture of a blind estimation system is proposed and its performances are proved by simulations.
