Abstract: Correct synchronization is essential for CDMA mobile communication system. In this report, a typical DS-CDMA receiver model is simulated: Six user signals, encoding with different PN codes, are transmitted through Rayleigh fading channels with three paths per channel and summed. Different environment parameters including clock drift and additive white guassian noise are used. The signal is then correlated with a locally generated PN code by means of a matched filter. To obtain the symbol synchronization information, several algorithms have been developed. The algorithms are analyzed and compared to study the pros and cons to different environment parameters.
