Summary This paper presents a new and exact expression for the bit error probability (BEP) of the square M ‐ary quadrature amplitude modulation ( M ‐QAM) scheme, with the channel under double gated additive white Gaussian noise (G 2 AWGN) and η ‐ μ fading in a communication system using the spatial diversity technique. The expression for the BEP is written in terms of the Appell function. The BEP curves are presented under different values of the number of branches of the maximum ratio combining (MRC) receiver, order of the constellation M , and parameters that characterize mathematically the channel, corroborated by simulations performed with Monte Carlo method.
