Abstract
The UWB system is a promising technology that can provide high-data rate and robustness to multipath fading. However, because of the difficulty in analyzing the UWB channel models adopted by the IEEE UWB 802.15.3a Task Group, previous analytical works regarding transmitted-reference systems are based on simplified channel models or computer simulations. Besides, the symbol duration is assumed to be sufficiently large so that the effect of intersymbol interference (ISI) can be ignored. In this thesis, the exact evaluation of the signal-to-interference-plus-noise ratio for differential transmitted-reference systems over the IEEE 802.15.3a channel structure is derived regarding the effect of ISI. A simplified formula is also provided for ease of the following system analysis. In particular, the optimal integration time for different symbol durations and channel models is studied. Some special phenomena due to ISI and a universal rule to approach the maximum SINR can hence be characterized. Compared with the previous methodology, our analytical results provide a more efficient and insightful way to receiver design and optimization.
