摘要：

In this paper, the performance of an MC-DS-CDMA (multi-carrier direct- sequence coded-division multiple-access) system working in Nakagami-m fading channels with correlation characteristics is studied. In order to avoid the difficulty of explicitly obtaining the pdf (probability density function) for the SNR (signal-to-noise ratio) at the output of Rake receiver, there is a pdf with the sum of Gamma varieties applied in the derivation of closed form for BER (bit error rate) performance. Two cases, single- and multiple-user exemplified for validating the fact that the performance degradation of the MC-DS-CDMA is sensitive to the correlation coefficient between the fading branches. Besides, the assumption of PBI (partial band interference) between the subcarriers is considered in this study.
