Abstract

In this paper, we derive a general expression for the bit error rate (BER) performance of an arbitrary square/rectangular Gray-coded quadratic amplitude modulation (QAM) scheme. This general formula requires a number of conditional probabilities which we derive in closed-form for independent and nonidentically distributed (i.n.d.) Rayleigh fading channels, when maximum ratio combining (MRC) with imperfect channel estimation (ICE) is employed. Our general formula determines the exact BER of any arbitrary square/rectangular QAM MRC receiver with ICE in i.n.d. Rayleigh fading channels, avoiding time consuming simulations. In addition, Monte Carlo simulations and analytical results are in excellent agreement.
