Abstract :
Code division multiple access (CDMA) systems are actively being considered for use in mobile environments. In this paper, new analytical expressions for the bit error rate (BER) of an asynchronous direct sequence (DS) CDMA system employing noncoherent binary demodulation in a Nakagami multipath fading channel are derived. Two binary demodulation schemes are considered, namely, the differential phase shift keying (DPSK) and the square-law demodulation with orthogonal spreading sequences. In each case, the analysis assumes that an arbitrary number of independent but nonidentical resolvable paths are combined by a RAKE receiver
