This paper presents analytical solutions for the performance of a single relay aided amplify-and-forward (AF) direct sequence code division multiple access (DS-CDMA) system over Rayleigh/Nakagami-m fading channels.The source-destination channel is assumed to be Rayleigh distributed while relay-destination link is Nakagami-m distributed.First, a cumulative distribution function (CDF) is derived for the source-relay-destination link and the derived CDF expression is used to evaluate the outage probability.Then, a moment generating function (MGF) is obtained through integral evaluation of the derived CDF expression in order to evaluate the average error probability of the considered system.Finally, the accuracy of the proposed analytical expressions are confirmed by computer simulations.
