Abstract
We present a method for designing multi-dimensional multi-rate nonuniform band FIR filter banks with integer or rational decimation factors. The analysis is based on the periodically time-varying (PTV) impulse responses of the filter bank branches. A constraint is developed, in terms of the analysis and synthesis filters, which ensures perfect reconstruction of the input signal. This forms the basis for the design method which uses constrained optimization techniques. We review impulse response analysis of filter banks and use Smith normal form decomposition to simplify their structure. We show how these impulse response analysis techniques allow us to consider filter banks that previous techniques fail to address.
