摘　　要：根据宽带码分多址 (WCDMA)系统的特点 ,分析了导频符号辅助相干解调 (PSACD)的性能 ,基于此提出了一种适用于WCDMA系统的新型帧结构 ,理论分析和计算机仿真得到的结果表明随着车速的提高 。According to the characteristic of WCDMA system,performance loss of pilot symbol aided coherent demodulation (PSACD) is analyzed here.Based on this we put forward a novel frame structure,which is more suitable for WCDMA.Performance comparison between conventional frame structure and the novel one is evaluated by computer simulation.From the results it is clear that the higher the vehicle speed is,the better the performance will be.

关 键 词：码分多址 相干解调 信道估计
