Ultra Wideband Communications: from Analog to Digital (2012)
Abstract / truncated to 115 words
The aim of this thesis is to investigate key issues encountered in the design of transmission schemes and receiving techniques for Ultra Wideband (UWB) communication systems. Based on different data rate applications, this work is divided into two parts, where energy efficient and robust physical layer solutions are proposed, respectively. Due to a huge bandwidth of UWB signals, a considerable amount of multipath arrivals with various path gains is resolvable at the receiver. For low data rate impulse radio UWB systems, suboptimal non-coherent detection is a simple way to effectively capture the multipath energy. Feasible techniques that increase the power efficiency and the interference robustness of non-coherent detection need to be investigated. For high data ... toggle 8 keywordsultra wideband communications – non-coherent detection – time-hopping – pulse position modulation – analog-to-digital converter – widely linear – non-circular – reduced rank
