Abstract
A DCT-based simplified general structure for a linear phase paraunitary filter bank (LPPUFB) was developed by the pre- and post-processing of the DCT in the time domain. The new structure can be viewed as the dual of the generalized LOT (GenLOT). We generalize the result to odd-channel LPPUFB and LPPUFB with pair-wise mirror image property. Design examples and their application in image compression are presented.
