On efficient implementation of oversampled linear phase perfect reconstruction filter banks
Jie Liang, Lu Gan, Chengjie Tu, Trac Duy Tran, Kai‐Kuang Ma · 2003
In this paper, we first present an alternative way of generating over-sampled linear phase perfect reconstruction filter banks (OSLP-PRFB). We show that this method provides the minimal factorization of a subset of existing OSLPPRFB. The combination of the new structure and the conventional one leads to efficient implementations of a general class of OSLPPRFB. Possible application of the new scheme is discussed.
