A polyphase and FFT realization of modulation sub-band adaptive filter with minimum sampling rate

Abstract

A sub-band adaptive lter, in which modulation and demodulation are employed, were proposed [1],[2]. The sampling rate can be minimized, while no aliasing occurs. In this paper, a polyphase and FFT realization of this sub-band adaptive lter is proposed. In the polyphase and FFT realization for the transmultiplexer [3], the sampling rate reduction is the same… (More)
