Abstract :
Product combining (PC) is a well known diversity technique that effectively combats the effect of partial-band jamming (PBJ) affecting fast-frequency-hopping/frequency-shift-keying systems. We rely on the theory of H-function random variables to present an approach for the average BER evaluation of PC over partial-band jammed Rayleigh fading channels. The final closed-form formula is expressed in terms of the Meijer G-function, which can be easily evaluated using common mathematical software for small values of the diversity order. Based on this result we also develop an infinite series representation for the average BER. Numerical experiments show that the latter series representation offers a speed-up factor in evaluating the average BER especially for high values of the diversity order. The mathematical formalism is illustrated by some numerical examples showing the effect of various parameters on the performance of the system
