Implementation of MIMO-OFDM with Zero Forcing Equalization

Abstract

In wireless communication, the receiver side BER strongly affected by channels noise, interference, distortion, synchronization error and wireless multipath fading channels, Multiple-input and multiple-output (MIMO) and system is the use of multiple antennas at both the ends to enhance spectral efficiency while channel equalization is mandatory to mitigate the effects of channel induced distortions. The obtained results demonstrate that spatial diversity along with the equalization significantly improves the error performance in frequency selective wireless fading channels. In this Paper, we propose a MIMO system with Orthogonal Frequency Division Multiplexing (OFDM) with zero forcing equalization. This Paper presents, a simulation system is implemented using different fading communication channel to study the performance analysis of Bit Error rate (BER) Vs Signal to Noise ratio (SNR).
