Abstract

In this paper, we present a power efficient digital front-end for cognitive radio and software-defined radio. The proposed architecture is based on a perfect reconstruction polyphase filter bank able to support a variable number of channels. As an example, we present the implementation of a configurable channelizer working in 8-channels or 4-channels mode. Power efficiency is obtained by switching off the unused resources in the not operating modules. The power saving are estimated through extensive simulations.
