摘要： 针对第三代移动通信系统WCDMA(FDD)频分多址下行链路的结构,提出了一种新的利用公共导频信道和专用数据信道进行加权的联合信道估计方法.仿真表明该方案能有效地估计出低速和高速的信道参数,使Rake接收机的性能比传统的只利用公共导频进行信道估计的方案有了明显的改善.

关键词: 信道估计, 多时隙加权平均, 宽带码分多址

Abstract: A novel scheme is proposed for channel estimation of WCDMA down link where a pilot channel is simultaneously combined with a data traffic channel. The proposed scheme exploits channel information in both pilot and data traffic channels by combining channel estimates from these two-channels. The computer simulation results show that the performance of the Rake receiver is improved effectively.

Key words: WMSA, Channel Estimation, WCDMA
