摘要：

An efficient weighted L-p algorithm for the design of linear-phase cosine modulated filter bank is proposed. The filter bank design process is formulated as an iterative least-squares optimization problem. Our algorithm minimizes the pth power of the error function, where p may vary in different frequency bands. The algorithm is therefore very flexible, since different L-p error criteria can be used at different frequency bands. Design example is presented for illustration. It is shown that good designs can be obtained with the new algorithm.
