Abstract

This paper addresses the performance of Multiple-Input-Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM), MIMO-OFDM communication system in environments where the interfering noise exhibits non-Gaussian behavior due to impulsive phenomena. It presents the design and simulation of an adaptive receiver technique that aims to minimize the effect of impulsive noise on the performance of the MIMO-OFDM communication system under Additive White Gaussian Noise (AWGN) channel. The proposed adaptive technique uses three different types of algorithms, an Adaptive Recursive least Square (RLS), Adaptive Normalized Least Mean Square (NLMS), and Variable Step-size Adaptive Normalized Least Mean Square (VSNLMS). The real concern in generating the impulsive noise is to have the main characteristics that emulate the actual impulsive noise. Hence the impulsive noise is generated and modeled based on reference [4] using Matlab/Simulink. The bit-error-rate (BER) performance of the MIMO-OFDM system in an impulsive noise environment was evaluated. The proposed adaptive receivers' technique offers a novel approach in reducing the effect of the impulsive noise in MIMO-OFDM system.
