EQUAL-GAIN DIVERSITY RECEPTION IN MFSK/FFH SPREAD SPECTRUM MULTIPLE-ACCESS COMMUNlCATION SYSTEM

摘要

The symbol error probability of equal.gaindiversity reception in a fast frequency hopped spread spectrum multiple-access communicationsystem with M-ary frequency-shift keying modulation is obtained.It is assumed that the system operates through a frequency-selective slow-fading Rayleigh channel coupled with other user interference and additive white Gaussian noise.The effect on the system perform ance of unequal signal-noise ratios in different diversity channels is investigated.Numerical results show that the system performance can be significantly improved by means of equal-gain diversity.
