摘　　要：文章在深入研究WCDMA下行链路的信道结构及接收信号处理流程基础上,提出了一种在Rake接收机中,通过对P-CPICH(主公共导频信道)序列两次相关检测实现频偏估计的算法;同时,对该算法主要性能指标进行了分析及仿真,验证了算法的可行性。Base on deeply studying the channel structure and processing procedure of WCDMA downlink,the paper propose a frequency offset estimation algorithm in Rake receiver in WCDMA;The algorithm adopt twice correlation operation by P-CPICH pre-defined bit sequence;simultaneity,the paper give some key parameters analysis and performance emulation to prove feasibility of the algorithm.
