Abstract

Taking into account the ad-hoc and time variant nature of orthogonal modulation communications systems, the blind estimation techniques are preferred for messages estimation. In this paper we prove that the denoising, one of the most important application of wavelets theory, can be used as blind estimation method in Single Carrier Frequency Division Multiplexing (SCFDM) systems, which are used for the uplink multiple access in 3GPP Long Term Evolution (LTE) technology. The architecture of a blind estimation system is proposed, and its performances are highlighted by simulations.
