本文研究了如何用提升方法构造M带PR -FIR滤波器组 ,并且考虑了一种特殊情形的线性相位 (LinearPhase ,LP)性质 ,及其优化设计问题 ,即如何转化为一个二次型优化问题 .
This paper studies how to construct the M-band PR-FIR filter bank by using the lifting method, and considers the linear phase (LP) property of a special case and its optimization design problem, that is, how to transform it into a quadratic optimization problem .
