Abstract:
A research gap exists in analyzing the exact performance of wireless systems that employ selection combining diversity technique with Meijer-GlFox-H function representation for signal fading. In this paper, we develop a general framework to analyze the exact performance of wireless systems that employ the Meijer-G function with integer exponents for statistical characterization. We derive exact analytical expressions for the average bit-error rate (BER) for multi-aperture underwater wireless optical communication (UWOC) system operating over exponential-generalized gamma (EGG) oceanic turbulence combined with pointing errors. We also develop asymptotic expressions at a high signal-to-noise (SNR) to capture insights into the system's performance. Our simulation findings confirm the accuracy of our analytical expressions and illustrate that the exact expression may provide a better estimate for the efficient deployment of UWOC.
