本文对用控制信道中的导频符号、采用多时隙加权平均（ ＷＭＳＡ－ｗｅｉｇｈｔｅｄ ｍｕｌｔｉ－ｓｌｏｔ ａｖｅｒａｇｉｎｇ）信道估计技术的ＷＣＤＭＡ上行链路进行了性能仿真研究。仿真结果表明，参与信道估计的时隙（ｓｌｏｔ）数目、加权系数的选取应针对不同的信道衰落环境。结合仿真结果，讨论分析了前向纠错、ＲＡＫＥ接收机的指峰数及信道中可分解路径的平均功率之差对ＷＣＤＭＡ上行链路性能的影响。
In this paper, the performance simulation of WCDMA uplink using pilot symbol in control channel and WMA-weighted multi-slot averaging channel estimation technique is performed. Simulation results show that the number of slots participating in channel estimation and the selection of weighting coefficients should be aimed at different channel fading environments. Combined with the simulation results, the influence of the difference between the forward error correction, the number of fingers of the RAKE receiver and the average power of the resolvable paths in the channel on the WCDMA uplink performance is discussed.
