Performance of UWB signals with different transmission and reception schemes in multipath channels

This paper presents the performance of UWB communication signals over Multipath fading channels, the chosen multipath fading channel is the UWB multipath indoor NLOS channel based on the modified Saleh-Valenzuela (S-V 3) model. Also, a practical comparison between the UWB signal over Multipath NLOS channel using DS-UWB with BPSK data modulation and TH-UWB with pulse-position-modulation (PPM) schemes which are the two major transmission and multiple access techniques, is presented. This comparison includes two important receivers used for UWB signals´ detection these are; the UWB Rake receiver and the minimum-mean-square-error (MMSE) receiver using MATLAB simulations, considering the 6^th derivative of the Gaussian monocycle.
