| 摘 要： | ＣＤＭＡ２０００采用多载波和直接序列扩频两种方式来达到提供宽带数据业务的目的。针对ＣＤＭＡ２０００前向信道的三载波调制方式，提出了一种基于带通ＲＡＫＥ接收机的多载波解调方法。这种方法避开了设计多比特的基带数字滤波器，从而大大降低了实现的复杂度。文章首先分析了三载波的调制结构。根据ＲＡＫＥ接收机的原理，推导出相应的带通ＲＡＫＥ接收机模型并给出解调结构，最后，用ＳＰＷ软件对此模型进行仿真并给出了传真结

| Abstract: | Multi-carrier and direct-spread-spectrum are employed by CDMA2000 to support wideband data service. A novel demodulation approach is proposed for multi-carrier based on band-pass RAKE receiver. Without multiple-bit low-pass digital filter, the complexity of receiver can be reduced greatly. In this paper, the structure of multi-carrier is illustrated and the principle of REKE receiver is discussed. Then, the structure of band-pass RAKE receiver and the model of demodulation are depicted. Simulation results about the system performance are also presented. |
