Exact Symbol Error Probability of Square M-QAM Signaling over Generalized Fading Channels subject to Additive Generalized Gaussian Noise

摘要

This paper considers the average symbol errorprobability of square Quadrature Amplitude Modulation (QAM)coherent signaling over flat fading channels subject to additivegeneralized Gaussian noise. More specifically, a generic closedformexpression in terms of the Fox H function and the bivariateFox H function is offered for the extended generalized-K fadingcase. Simplifications for some special fading distributions such asgeneralized-K fading, Nakagami-m fading, and Rayleigh fadingand special additive noise distributions such as Gaussian andLaplacian noise are then presented. Finally, the mathematicalformalism is illustrated by some numerical examples verified bycomputer based simulations for a variety of fading and additivenoise parameters.
