Influence of impulse noise on alamouti code performances

Abstract

Multiple-Input Multiple-Output systems ensure spatial diversity and fading protection for wireless communications. This paper addresses the impulse noise described by the Middleton Class-A statistical model, which can affect their performances. We have analyzed the influence of impulse noise, described by Middleton Class-A non-Gaussian model on the performances of the Alamouti code, with two transmitting antennas and two receiving antennas, on channels affected by Rayleigh fading, with Binary Phase-Shift Keying modulation. The simulations were made for different parameter values of the noise model and they showed that as the Signal-to-Noise Ratio increases, the performances decrease for the impulse noise compared with the Gaussian one. It is shown that BPSK modulation is more robust than QPSK one, used in transmission over impulse noise environment using an Alamouti code. © 2014 Springer International Publishing Switzerland.
