摘　　要：研究了基于维纳滤波的导频符号辅助信道估计方法在自适应Turbo编码调制(TuCM)中的应用.以能反映信道估计质量的估计误差的方差为评价标准,分析与仿真了在实际应用中,信道估计误差对自适应TuCM的性能影响.Channel estimation is either the premise or one of the key factors for achieving its good performance. The pilot-symbol-aided channel estimation with Wiener filter was applied to adaptive turbo code modulation (TuCM). On the basis of estimation error variance, the performance influence due to channel estimation error was analyzed and simulated.
