摘　　要：通过一种新的方法构造酉矩阵,将该酉矩阵替代多级维纳滤波器(MWF)中的分解滤波器,得到一种新的降维多级维纳滤波器(RDMWF)。根据表达式给出了有效实现结构,并证明了该滤波器是一种酉多级滤波器(RUMWF)。相比于常规级维纳滤波器实现算法,新算法的计算量得以进一步降低且干扰抑制性能不受影响。An unitary matrix is constructed with a novel method, the filter-bank part of the Multistage Wiener Filter （MWF） is formed by applying the unitary matrix, and a new Reduced-Dimension Multistage Wiener Filter （RDMWF） is developed. The RDMWF is proved to be a Unitary MWF （RUMWF） and an efficient architecture is also developed. Compared with implementing algorithm of the common MWF, the new implementing algorithm needs fewer operations and maintains performance.
