Abstract
The bit-error rate (BER) for a forward-link cellular direct-sequence code-division multiple-access (DS-CDMA) system is evaluated. This analysis takes into account the effects of multi-cell interference resulting from Nakagami multipath fading, frequency selectivity, path loss and mobile user spatial distribution. Exponentially decaying multipath intensity profile (MIP) is adopted in the model to investigate its significance on the overall performance. In order to evaluate the BER performance efficiently, saddlepoint integration (SPI) is applied in the analysis. By fixing the number of resolvable multipaths and varying the number of fingers for the RAKE receiver, it can be shown that the capacity of a DS-CDMA cellular system increases almost linearly with the number of RAKE fingers.
