Abstract
The aim of this paper is to analyze the effects of nonlinear distortions caused by the high power amplifier (or other nonlinear devices) and additive gaussian noise in direct-sequence code-division multiple access (DS-CDMA) systems. Analytical expression for the conditional and total probability density functions for the multiplexed CDMA signal had been derived, which could be used for obtaining the accurate error rate of the system and for specifying technical specifications for the baseband channel of DS-CDMA systems.
