Performance analysis of generalized QAM modulation under η-μ And κ-μ fading

Abstract

This paper presents new closed-form expressions for the symbol error probability (SEP) of θ-QAM modulation with maximum ratio combining (MRC) receiver under η-μ and κ-μ fading. The SEP formulae, obtained from the definite integrals of the moment generating function (MGF) of the signal-to-noise ratio (SNR) at the input of the MRC receiver, are written in terms of Lauricella functions. The numerical evaluation of the expressions is carried out for the η-μ distribution, which includes important distributions as special cases, such as Hoyt, Nakagami-m, Rayleigh, and one-sided Gaussian, as well as for the κ-μ distribution, which includes Rice, Nakagami-m, Rayleigh, and one-sided Gaussian as special cases. © 2013 Queiroz et al.; licensee Springer.
