Average BER Performance of Orthogonal Space-Time Block Coding System with Antenna Selection Over Generalized eta-mu Fading Channel

Generalized channel fading distributions such as kappa-mu and eta-mu are well suited for modelling various fading channels as they fit well to the experimental data. This paper is concerned with the performance analysis of orthogonal space-time block-codes system using M-ary Phase shift keying/quadrature amplitude modulation with antenna selection over generalized eta-mu fading channel i.e., for non-line-of-sight applications. We derive the closed form expression of the average bit error rate by employing "moment generating function" based approach for different modulation schemes. Simulation results are finally presented to demonstrate the correctness of theoretical analysis by assuming different values for eta and mu, where each value corresponds to different channels. The impact of actual number of antennas, i.e., number of antennas before antenna selection, were also shown.
