摘要
给出了偶数与奇数长度矩阵共轭正交滤波器(MCQFs)的转换关系,并且给出了由低阶MCQFs派生出高阶MCQFs的方法.通过这种方法构造的MCQFs同样满足完全重构条件.
The relationship between even-length and odd-length matrix conjugate quadrature filter (MCQFs) was introduced.A set of rules for deriving higher MCQFs from a lower one was established.A newly constructed MCQFs also satisfied the perfect reconstruction condition.
