Cellular Mobile Communications have become an essential part of the world telecommunications. However, the systems suffer from multipath propagation effects. In this paper, we calculate the probability of symbol error rate and bit error rate of M-ary Quadrature Amplitude Modulation (M-QAM) over slow, flat, identically independently distributed Rayleigh fading and additive white gaussian channels. Since the fading is one of the major constraints in wireless communications, then diversity modulation technique is used for the efficient transfer of message signals. The simulation results show between SER/BER and energy per bit to noise spectral density.
