摘要：
In order to suit with non-equal bandwidth signals which result from various services in communication applications, a nonuniform subband method with nonuniform general parameter filter banks (GPFBs) implemented by tree-structure system based on two-channel equal bandwidth filter banks is proposed. GPFBs are utilized to partition the frequency band into several subbands without aliasing between them. With subbands running at downsampling and in manner of parallel, the loads of computational processing costs, compared with conventional fullband methods, can be alleviated. Deep suppression of the interference and convergence speed of weights are also improved.
