Error analysis of selection combining over α–μ fading with symmetric alpha-stable noise

Abstract

In this paper, error performance of a communication link subjected to a non-Gaussian noise model known as symmetric alpha-stable (SαS) noise and α−μfading environment is analyzed with selection combining at the receiver. To this end, using binary phase-shift keying (BPSK), closed-form expressions of exact and asymptotic bit-error-rate (BER) are obtained. Furthermore, closed-form expressions of outage probability and n-th moment are obtained. From the n-th moment, the average signal-to-noise ratio (SNR) and channel quality estimation index (CQEI) are calculated. The effect of the number of antennas (L) and the fading parameters on the BER is studied for different impulsive settings. Monte-Carlo simulations are performed to validate the derived results.
