level, the Non-Linear (NL) distortions due to the HPA (High

Power Amplifier).-In this paper, we present a method based on Neural

Network (NN) technique and accompanied with MMSE

(Minimum Mean Square Error), which corrects at the receiver

level, the Non-Linear (NL) distortions due to the HPA (High

Power Amplifier). The neural network consists on a feedforward

Multi-Layer Perceptron (MLP) associated with

Levenberg-Marquardt learning algorithm. The results show

that the neural network compensator brings perceptible in a

complete VBLAST MIMO OFDM (Vertical Bell Laboratories

Layered Space-Time Multiple-Input Multiple-Output

Orthogonal Frequency Division Multiplexing) system running

under a Rayleigh fading channel.
