Generalized polyphase representation and application to coding gain enhancement
A.K. Soman, Palghat P. Vaidyanathan · IEEE Transactions on Circuits and Systems II Analog and Digital Signal Processing · 1994
Generalized polyphase representations (GPP) have been mentioned in literature in the context of several applications. In this paper, we provide a characterization for what constitutes a valid GPP. Then, we study an application of GPP, namely in improving the coding gains of transform coding systems. We also prove several properties of the GPP.>
