Abstract

This paper proposes a statistical model of the wideband code division multiple access (W-CDMA) signals. The performance of a W-CDMA system is evaluated by calculating the average bit error rate (BER) which is derived from the probability distribution of the W-CDMA receiver output. If a statistical model of the receiver output is available, the performance evaluation becomes much simpler and it enables diverse analyses of the system for channel coding and other purposes. In this paper the statistical model of W-CDMA signals, more specifically those of the receiver outputs, is represented as a Nakagami-m distribution, considering two cases of bandwidths and channel environments. The adequacy of a statistical model is verified by chi-square test of 1% significance level and the comparison of BER obtained from simulation data and the statistical model
