Toward digital UWB radios: part II - a system design to increase data throughput for a frequency domain UWB receiver

For pt.I see ibid., p.248-52. Our UWB receiver, which is based on the frequency domain approach, samples spectral components of the received signal at the pulse repetition rate, and processes the signal in the frequency domain (Lee, H.-J. et al., Proc. IEEE Conf. Ultra Wideband Systems and Technologies, p.86-90, 2003). Our receiver effectively increases the sampling rate through signal processing. We investigate efficient synchronization and equalization schemes to mitigate intersymbol interference, which is critical for high data rate applications. The proposed schemes improve the performance over a conventional analog correlator type receiver by 1-4 dB.
