对于广义多信道的最小二乘自适应滤波，即允许有信道参数数目不相等，本文提出一种QR格型算法。这个算法完全利用Givens旋转来解广义多道最小二乘问题，具有优越的数值性能和高度的模块化结构，适合于VLSI实现。对于通用处理器实现，这个算法需要O（p2）运算复杂度，其中p为信道数，对于基本处理单元实现，需要2p角度计算单元和3p2－p旋转单元。 For the generalized multi-channel least-squares adaptive filtering, that is, the number of allowed channel parameters is not equal, this paper presents a QR lattice algorithm. This algorithm fully utilizes Givens rotation to solve generalized multichannel least squares problems, has superior numerical performance and highly modular structure, and is suitable for VLSI implementation. For a general-purpose processor implementation, this algorithm requires O (p2) computational complexity, where p is the number of channels and requires 2p angle and 3p2-p rotation units for the basic processing unit implementation.
