New low-complexity adaptive receivers are proposed for time-hopping binary phase shift keying ultra-wide bandwidth systems with multiple users. Both additive white Gaussian noise and multipath fading channels are considered. Numerical results show that the new adaptive receivers outperform the conventional matched-filter receivers in both additive white Gaussian noise and multipath fading channels,...
The sensitivity of the system capacity to the synchronization error is analyzed for a time-hopping direct-sequence binary phase shift keying transmitted-reference ultra-wide bandwidth receiver. Both additive white Gaussian noise and multipath fading channels are considered. Numerical results show that the Gaussian distributed synchronization error gives the highest capacity and that there is an optimum...
