摘　　要：根据区域内移动通信网信号接收的需求,提出了一种复杂环境下低信噪比WCDMA移动通信信号接收系统的总体设计方案,针对关键环节小区搜索采用了差分相干累积和RS译码判决等改进措施,提高了低信噪比WCDMA信号的处理性能。仿真和实验证明了改进措施的有效性。According to the signal reconnaissance of mobile communication system in a cevain area, a top design of low SNR WCDMA mobile communication signal receiving and processing system in complex environment is in- troducod. An optimized cell seraph scheme is adopted by using differential coherent accumulation and RS decoder and the performance of low SNR WCDMA signal processing is improved. Computation and experiment confirm the effectiveness of the optimized scheme.
