基于几何分析方法的去相关自适应滤波器的快速算法研究

Adaptive filtering algorithms are discussed and a fast algorithm is proposed based on vector plots analysis, which is.different from the present adaptive filtering algorithms. It applies.the approaches of mathematical geometrical analysis into the study of adaptive filtering and tries to seek an effective and fast algorithm on the basis of geometrical analysis, through inquiring into vector plots structure of least mean square (LMS) algorithm and geometrical.feature of algorithm convergence. Numerical simulations indicate the.efficiency and superiority of this new algorithm. Thus, a new approach.is in prospect for the research of adaptive filtering algorithms.

突破自适应滤波理论的传统研究方法，针对目前国际上对多路回波消除研究中遇到的瓶颈问题（由各路信号的强相关性而引起的滤波器性能下降），探索建立自适应滤波理论的深入研究开劈另一条全新的途径。
