基于隐训练序列的信道估计改进方法

摘要

在准静态信道条件下，针对短波信道的时变抽头系数 FIR 模型，给出了一种改进的基于不相关特性隐训练序列的信道估计方法。通过对发送的信息序列进行实际数据帧的零均值处理，使信道估计性能得到了改善。%An improved channel estimation method using uncorrelated implicit training sequence is given in a quasi-static channel considering time-varying coefficient FIR model of HF channel .Channel estimation performance is improved by mak-ing practical frame data zero in information transmitter .
