摘要

将一种有效的盲信道识别技术扩展到复杂信道和数据。该方法是极大似然估计的一种变体，对于小(残余)失真和大样本量，该方法接近Cramer-Rao界，被推荐作为盲反卷积的最后一步。在分析了输入数据的一般概率密度函数后，考虑了数字传输系统中使用的“方形”和“圆形”pdf和PSK星座。

Blind estimation of a complex channel impulse response

Extends to complex channels and data an efficient technique for blind channel identification. The method, which is a variant of maximum likelihood estimation, approaches the Cramer-Rao bound for small (residual) distortion and large sample size, and is recommended as a final step of blind deconvolution. After an analysis for general probability density functions of input data, 'square-' and 'round-shaped' PDFs, and PSK constellations used in digital transmission systems are considered.<>
