Performance of mobile networks under composite F fading channels

In this paper, the performance of a mobile wireless communication network operating over the Fisher-Snedecor F composite fading channel is analyzed. Specifically, a multi-antenna base station transmits information to a single-antenna mobile receiver, which employs the maximal-ratio transmission technique to improve the quality of the received signal. The well-known random waypoint mobility model is assumed to characterize the mobility of the receiver. Under this mobility scenario, we derive exact closed-form expressions for the probability density function, cumulative distribution function, and consequently for the Outage Probability (OP), the average Bit Error Rate (BER) for different digital modulation schemes, and the average channel capacity. To shed light into the impact of different channel parameters, simple asymptotic expressions at the high SNR regime are obtained for the OP and average BER. To validate our analytical expressions, the comprehensive Monte-Carlo simulations are conducted under various configurations and both results are in excellent agreement.
