Performance of optimum wavelet for DS-CDMA chip waveform over multi-path Rayleigh fading channels

In this paper, the probability of error (Pe) expression of asynchronous direct sequence-code division multiple access (DS-CDMA) signals using band-limited chip waveforms is derived over multi-path Rayleigh fading channels. In receiver, a matched filter-based rake receiver in conjunction with maximum ratio combiner (MRC) is considered. Numerical values for the P e are calculated for various chip waveforms including an optimum wavelet waveform. Analytical results are verified by conducting simulations. Results show that the optimum wavelet-based scheme outperforms time-limited raised cosine, half sine, rectangular and band-limited square-root raised cosine chip waveform-based schemes in terms of the Pe and the capacity defined as the number of users per Hertz for a same Pe level.

In this paper, the probability of error (Pe) expression of asynchronous direct sequence-code division multiple access (DS-CDMA) signals using band-limited chip waveforms is derived over multi-path Rayleigh fading channels. In receiver, a matched filter-based rake receiver in conjunction with maximum ratio combiner (MRC) is considered. Numerical values for the P e are calculated for various chip waveforms including an optimum wavelet waveform. Analytical results are verified by conducting simulations. Results show that the optimum wavelet-based scheme outperforms time-limited raised cosine, half sine, rectangular and band-limited square-root raised cosine chip waveform-based schemes in terms of the Pe and the capacity defined as the number of users per Hertz for a same Pe level.
