| Abstract | The performance of a direct sequence code division multiple access (DS/CDMA) system is
typically dependent on the signature codes used and a receiver structure. In this research, the
performances in terms of signal to noise ratio (SNR) and bit error rate (BER) of a bipolar
baseband DS/CDMA system is investigated. An analysis of the Optimum matched filter for bipolar
baseband DS/CDMA applications is shown. The filter coefficients are found which maximize the
output signal to noise ratio. A performance comparison of this filter with a conventional matched
filter is demonstrated. The Gold codes and random binary sequences are used in this investigation.
The performance investigation for CDMA techniques in an urban area Rayleigh fading radio
channel is also presented. The simulation results demonstrated that the optimum matched filter
receiver together with the forward error correction coding can achieve a very good system
performance, in the mobile radio channels.
