This paper presents a compensating method based on Neural Network (NN) of Non-Linear (NL) distortion, which caused by High Power Amplifier (HPA) in Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO OFDM) systems. In this work, we present and we evaluate with simulation, the effect of nonlinearity on the system capacity and the performance of NN compensator accompanied with Minimum Mean Square Error (MMSE) receiver in a VBLAST (Vertical Bell Laboratories Layered Space-Time) MIMO OFDM systems running under a Rayleigh fading channel.
