| Abstract | ||
| Due to enormous growth of Wireless Personal Area Network (WPAN) service, the need of a new engineering technique that can transmit high data rates arises. With its wide bandwidth, Ultra Wideband (UWB) has the potential to offer much higher capacity than the current narrowband system. In this research, a new Rake receiver for a pulse based UWB communication system is proposed in a multipath channel environment to mitigate the multi-user interference (MUI). The conventional Rake receiver is capable to mitigate the MUI to a certain limit because it contains only one decision unit. The proposed Rake receiver is based on modifying the conventional Rake receiver in order to mitigate the MUI by using three-stages-decision unit. The results are illustrated by using Matlab program that validate the proposed Rake receiver. Theperformance of the proposed Rake receiver is evaluated using a Partial Rake (PRake). The Bit Error Rate (BER) performance of the proposed Rake receiver is improved as compared with the conventional Rake receiver. | ||
