Performance of Multihop Wireless Networks in alpha-mu Fading Channels Perturbed by an Additive Generalized Gaussian Noise

摘要

In the literature, the performance of multihop wireless networks is extensively analyzed over various fading channels subject to an additive white Gaussian noise (AWGN). However, and to the best of authors' knowledge, the generalized Gaussian noise case has not been considered before. Motivated by this, we therefore analyze the system performance-in terms of the average bit error rate-of a multihop wireless communication system that operates over the alpha-mu fading channels perturbed by an additive white generalized Gaussian noise (AWGGN). To this end, we obtain an exact closed-form expression for the average bit error rate (BER) for M-ary quadrature amplitude modulation (M-QAM) over the alpha-mu fading channels with AWGGN. Some representative numerical results are presented to study the influence of the fading parameters, as well as the influence of the shaping noise parameter. These results are supported with Monte-Carlo simulations to validate our analysis.
