这是一篇很好的有关信道估计的文章，

可以用来快速的了解信道估计的基本内容-and MAI induced by multiple-input, multiple-output channels. In particular, this article

reviews the typical inverse filter criteria (IFC) based algorithm, super-exponential algorithm,

and constant modulus algorithm along with their relations, performance, and improvements.

Several advanced applications of these algorithms are illustrated, including

blind channel estimation, simultaneous estimation of multiple time delays, signal-tonoise

ratio (SNR) boost by blind maximum ratio combining, blind beamforming for

source separation in multipath, and multiuser detection for direct sequence/code division

multiple access (DS/CDMA) systems in multipath.
