Bit Error Probability of M -QAM Subject to Impulsive Noise and Rayleigh Fading


In this paper exact expressions are presented for the bit error probability (BEP) of M -ary Quadrature Amplitude Modulation (M -QAM) signals subject to Double Gated Additive White Gaussian Noise (G 2 AWGN) combined with Rayleigh fading. In this study, the Rayleigh fading channel can be seen as a channel subject to an additive noise, R, obtained by the ratio between the received signal and the fading amplitude. Besides, for each model of impulsive noise considered, the probability density function (PDF) of R is presented, which is defined as the ratio between the random variable of the impulsive noise and the random variable of the fading.
