【摘要】 本文提出了一种跳频小波包分多址(FH-WPDMA)通信系统模型，分析讨论了该系统在多径衰落时变信道下采用判决反馈均衡的接收性能，采用空间分集接收，可显著降低系统的误码率。该系统易于支持多速率话音和数据业务，具有频谱利用率高，抗窄带干扰能力强和保密性高等优点。更多还原

【Abstract】 ： A wavelet packet function based FH-WPDMA communication system is presented. This system employs antenna diversity and decision feedback equalization. Simulation results show that the new multiple access system has good BER performance，high spectrum efficiency，high security and good narrow band interference rejection capability. Furthermore，the proposed system is also easy to support multi-rate voice and date services.更多还原
