| Description: | Graduation date: 2006 This thesis presents a channelized digital receiver design for UWB sytems in a multipath indoor environment. The UWB technology has been used for commercial and military purposes due to a number of advantages such as low-power consumption, noise-like and carrier free. The energy of UWB signal is spread over a wide range from near d.c. to a few gigahertz. For this reason, the analog to digital converter (ADC) in the receiver must support an extremely high sampling frequency (at least Nyquist rate) and high resolution. By using a channelized digital receiver, the speed of ADC can be considerably relaxed. The received signal is split into several subbands and sampled at a fraction rate of sampling frequency. In multipath environments, we propose a receiver architecture which provides a robust immunity to multipath interference. The proposed receiver consists a collection of receivers. If the multipath signal energy increases, the decision can be made more accurate. |
