Abstract

Due to the very wide bandwidth of UWB system, it is hard if not impossible to design high speed and high resolution ADCs with today's technology. This problem can be solved if the received UWB signal is split into a number of subbands by power splitters, analog low-pass filters, mixers and digital filters. By doing this, each of subbands can be sampled at a fraction of effective sampling frequency. In this paper, we present a simpler channelized receiver architecture for UWB systems than previously published work. Moreover, we present a new, though more complex, channelized receiver design for UWB systems in a multipath propagation environment. We also show through simulation that this new receiver achieves very good BER performance.
