Abstract

This paper addresses two majors problems in today´s wireless network using MIMO-OFDM. In fact, the performances of such a network depend on the interference management and on the equalization. These two problems are closely linked to channel estimation algorithms. In this paper, we propose a resource sharing scenario combined with a blind channel estimation algorithm based on fourth order statistics of the received signal. The proposed scheme is compared to the existing T/OFDM scenario and simulation results show its outperformance.
