| Abstract | ||
| In this paper, a suboptimal Ultra-wideband Rake receiver is proposed and simulated to decrease the multi-user interference in multi-path channel. The proposed receiver is based on detecting a single pulse alone in the Rakes' fingers and supplying it to a decision or discriminator devices. After that, another discriminator unit is placed after the maximum ratio combining section to discriminate the metric value of the received bit. The obtained simulated results show that the proposed Rake receiver has the best performance in terms of achieving Low Bit Error Rates (BERs) as compared with the conventional Rake that does not include neither decision nor discriminator except the decision unit that decide the estimated bit. The proposed Rake receiver and the obtained results are simulated using Matlab 7 and the network simulator package ver. 2 (NS2). | ||
