摘要：

The authors introduce a new and non-trivial class of linear and nonlinear perfect reconstruction critically decimated filter banks. The filters consist of a simple cascaded architecture within the sub-sampled domain. The structures also allow filter banks which satisfy a stronger definition of critical decimation to be defined over module In integer arithmetic.
