摘要
具有线性相位的正交多滤波带的因子化问题已通过具有某种性质的仿酉矩阵的因子化得到.应用Gram-Schmidt正交化方法进一步研究了该矩阵的因子化,它能够分解成多个一阶仿酉矩阵与一个酉矩阵的乘积.进而通过多滤波带与这个仿酉矩阵的关系能够得到具有线性相应的正交多滤波带的因子化.
The factorization of the orthogonal multifilter banks with linear phase can be obtained by paraunitary matrix with some property. We aplly the reference [2] to study the factorization of this matrix, it can be decomposed into the product of some one order paraunitary matrices and an unitary matrix. Furthermore, using the relation between multifilter bank and the matrix, we can derive the factorization of this multifivter bank.
