摘　　要：为了解决小区容量提升这一宽带码分多址接入(WCDMA)系统商业运营与网络规划中的关键问题,在研究信道多址干扰抑制的基础上,提出了一种提高小区容量的新思路,即在抑制下行公共导频信道多址干扰的同时抑制主公共控制物理信道多址干扰,并给出了基于这种思路的新型Rake接收机的实现方案.仿真结果表明:该新型接收机相对于传统Rake接收机具有更好的误比特率和小区扩容等性能.An efficient scheme based on mitigating the multipath interference of not only Common Pilot Channel （CPICH）, but also Primary Common Control Physical Channel （PCCPCH） in Wideband Code Division Multiple Access （WCDMA） downlink was presented to improve the cell capacity. A new Rake receiver based on this scheme, whose implementation complexity was very low, was also designed. The simulation results demonstrate that the proposed receiver has superior performance in Bit Error Rate （BER） and improving the cell capacity to both the conventional Rake receiver without multipath interference mitigation and the CPICH interference mitigation receiver proposed in 3GPP technical specification.
