Performances of DS-UWB signals over the CM1 channel model

Abstract

In this paper, we investigate the probability of error performance of Direct Sequence Ultra Wide Band (DS-UWB) signals using various pulse shapes over the CM1 model of the Standard UWB channel. The considered pulse shapes are the first and second derivatives of Gauss waveform, Rayleigh waveform, and first four orthogonal modified Hermite waveforms. Results reveals that the probability of errors for all available pulse shapes over the considered channel are very similar for few users. However, by increasing the number of users, the performance differences start to appear in favor of Hermite pulses.

Comparisons of various pulse shapes for DS-UWB signals over the UWB channel

“…Besides, instead of calculating the values of the ACF for possible pulse shapes, some given values (0.1 and 0.3) of the ACF are used for the numerical BER calculations in Chen et al [2]. The recent paper is the extended version of Öztürk and Yılmaz [19].…”
