Abstract

New solutions are given for the capacity and spectrum efficiency of frequency hopped spread spectrum multiple access system(FH-SSMA) in a Nakagami interference environment. In this paper we derive a exact formulation of the deletion probability for a mobile environment and analyze the system capacity and spectrum efficiency in terms of the average bit error rate(BER). It is shown that the system capacity is decreased by 52% as the Nakagami fading parameter is reduced to 0.5 and the required signal to noise ratio(SNR) is above 25dB, to get the spectrum efficiency of 0.3.
