Abstract:On the basis of analyzing the principle of multicarrier DS-CDMA (MC-DS-CDMA), we propose a novel multiband complex wavelet based multicarrier DS-CDMA system in this paper by using the optimized multiband complex wavelet as multicarrier basis function. The system bit error rate (BER) performance is investigated over Nakagami fading channel. Without any cyclic prefix (CP), the proposed system can avoid the decrease of spectrum efficiency and data rate of conventional MC-DS-CDMA with CP. Consider the uplink, the … Show more
