摘要：
We study the optimum (in the minimum mean-square error sense) linear periodically time-varying deconvolution filter of finite size. We show that the filter can be in the form of lapped transform or multirate filterbank, and it includes the FIR Wiener filter as a special case. We demonstrate that the proposed filter always possesses a gain over the Wiener filter.
