Abstract
This paper presents the performance of uncoded and space-frequency block coded (SFBC) orthogonal frequency division multiplexing (OFDM) system for two recently proposed composite fading model i.e. Fisher–Snedecor (F) and κ-μ/gamma. Both models are adequate for wearable communication system. In this paper, we derive the exact and approximate expressions of average bit error rate (ABER) for uncoded and SFBC OFDM system using fast Fourier transform (FFT) and fractional Fourier transform (FrFT). Further, these generalized expressions reduce to special cases of both composite fading models. Particularly, M-ary quadrature amplitude modulation (MQAM) and M-ary phase-shift keying (MPSK) modulation schemes are considered to derive ABER expressions. The numerical results are compared with the previous results of Rayleigh and Nakagami-m distribution. Also, the Monte Carlo simulation results are provided to crosscheck the validity of derived expressions.
