摘　　要：符号间干扰是影响带限通信信道性能的重要因素之一 ,为提高系统性能 ,在接收端需采用均衡技术 ,盲信道均衡算法是现在的研究热点。迫零盲均衡算法充分利用了输出信号的统计特性 ,因此具有很好的应用前景。从理论上对目前具有实际应用价值的最小均衡误差、特征矢量分解等迫零盲均衡算法作了介绍 ,并提出了改进算法中值需解决和注意的问题。Intersymbol interference is one of the major factors that influence a band-limited communication system. In order to enhance the performance of the digital communication system, equalization technology is always adopted at a receiver. Blind channel equalization has attracted a lot of research interests. The algorithm has a bright application prospect because of its making best use of output sequence statistics. This paper introduces some practical algorithms such as minimal MSE, eigenvalue decomposition, and then brings forward the methods to improve the algorithm performance.
