Abstract

Polyphase DFT filterbank is an efficient structure for channelized receivers, but its flexibility limited by the fixed relationship between decimating factor and channel number. In this paper, a flexible and efficient channelized receiver structure was proposed based on weighted overlapadd filterbank; In the structure, shift of input signals substitute shift of time windows. Filter coefficients aré used to weight shifted signals rather than calculate convolution, DFT is employed after Signal weighting, overlapping and adding. The structure is equal with polyphase DFT channelizer mathematically, but avoids its strict condition. It's a generalized form of polyphase DFT structure. Simulation results show the effectiveness of proposed structure.
