摘要：

In this work, we propose a new approach to process received signals in the frequency-domain, which opens the possibility for CMOS implementation of all-digital ultra wideband receivers. The key idea for the proposed method is to extract the frequency components of the received signal and to perform signal processing in the frequency domain. The proposed receiver architecture relaxes the speed requirement of analog-to-digital converters and is highly suitable for a multipath rich environment such as UWB. Our simulation results indicate that the proposed receiver improves the SNR by about 3 dB at BER=10(-1) when compared with an analog receiver under multi-path channel conditions.
