Performance Analysis of MIMO-OFDM System Based on SVD scheme under multi path selective fading channel

Abstract

We consider in this paper a MIMO-OFDM wireless communication system based on pre-coding and SVD techniques, which the system has the feedback of CSI to the transmitted side. The multi path channel, delay spread, Rayleigh fading and channel noise are assumed in the simulation of the proposed system. The zero forcing method is applied for detection the data received. The goal of our study is to evaluate the BER performance and see it with different case. The BER resulted shows the improvement by using the SVD decomposition for the associated system of MIMO-OFDM. Particularly in the complex conditions of wireless channel where we considered ten paths for propagation the signals between transmitter and receiver sides. And also the contribution is appeared when the system studied keeps a good BER performance when the data rate is increased by using more transmit antenna. As we evaluated the BER of MIMO-OFDM system done for various sub-carriers and in two guard interval lengths for the OFDM system
