Abstract

The effect of non-ideal chip waveforms on the bit error rate (BER) performance of code division multiple access (CDMA) systems is analyzed. The waveforms considered include sine and raised cosine in addition to the ideal rectangular waveform. The waveforms are assumed to be time-limited to the chip duration and cause no interchip interference. The modulation type is differential phase shift keying (DPSK). The channel is modeled as a discrete set of Rayleigh faded paths, which makes the analysis appropriate for mobile cellular systems as well as indoor wireless communications. The receiver uses a matched filter (for despreading) and is followed by a RAKE type of receiver
