| 摘 要： | 文章在分析多载波扩频码分多址的基础上，利用优化生成的复小波包及变换，研究了一种基于复小波包的多载波CDMA系统在多径瑞利衰落环境下的上行链路性能。仿真结果表明该系统要优于通常的MC-CDMA系统和基于实小波包变换的MC-CDMA系统，具有良好的抗衰落能力。并采用多天线分集接收技术进一步完善系统性能，从而增强了系统抗多径干扰和多址干扰的能力，且得到了更低的误码率。

| Abstract: | On the basis of analyzing the principle of MC-CDMA, by means of generating the optimized complex wavelet packet and its transform, the uplink performance of MC-CDMA system based on the complex wavelet packet in multipath Rayleigh fading channel is investigated. Simulation results show that the proposed system outperforms the conventional MC-CDMA and real wavelet packet based MC-CDMA, with superior capability against the fading. Meantime, multi-antennas diversity receiver technique is exploited to improve the system performance further as to strengthen the system capability against multi-access interference (MAI) and multipath interference for lower bit error rate (BER). |
