摘要

提出了一种多码CDMA (MC-CDMA) rake接收机的新架构设计。它包含一个搜索模块，三个独立的胖手指模块和一个用于高速数据解调的合并器。根据沃尔什码信道的数量，我们比较了所提出架构与传统CDMA rake接收机的硬件复杂性。结果表明，当沃尔什码通道数为4和7时，我们提出的架构分别减少了12%和18.6%的门数。

A novel architecture design for multicode CDMA rake receiver

We propose a new architecture design for the Multicode CDMA (MC-CDMA) rake receiver. It contains one searcher module, three independent fat finger modules, and one combiner for the demodulation of high-rate data. We compare the hardware complexity of the proposed architecture with a conventional CDMA rake receiver in terms of the number of Walsh code channels. The result shows that our proposed architecture has a 12% and 18.6% reduction in gate count when the number of Walsh code channels is 4 and 7, respectively.
