In conventional communication systems, the noise at the receiver is usually assumed to be Gaussian. However, this assumption is not always valid if the signal is affected by impulsive noise. This paper analyzes the theoretical bit error probability (BEP) of M-ary quadrature amplitude modulation (M-QAM) (M >= 4) on Rayleigh fading channels with impulsive noise that has an alpha stable distribution. The derived theoretical BEP can be used to evaluate the performance of wireless communication system with impulsive noise and also provides a benchmark for determining coding gains. Furthermore, two closed-form approximations of the theoretical BEP are derived that provide good approximations of the actual BEP.
