DSP algorithm and system design for UWB communication systems

Abstract

Ultra-Wideband (UWB) communication is recognized as one of the most promising technologies for next generation Wireless Personal Area Network (WPAN). In this thesis, a novel blind Rake (BRake) structure is proposed for high data rate low power consumption UWB communication systems. It avoids the estimation of multipath channel which must be provided for conventional Rake receiver systems. The transceiver complexity is further reduced by using Analog-to-Digital Converter (ADC) working at sub-Nyquist sampling rate. The closed form bit error rate (BER) performance analysis is provided. Extensive simulations have been carried out which verified the theoretical analysis.
