Abstract

In this paper, the performance comparison of PPM-TH, PAM-TH, and PAM-DS UWB for a single user link are analyzed for different data rates using the proposed UWB channel model from IEEE 802.15.3a. The Rake receivers with a pulse-matched filter via correlation mask are numerically evaluated with channel estimator algorithm. DS-UWB and TH-UWB with antipodal modulation perform basically the same. However, since TH-UWB is more difficult to synthesize, the conclusion is that DS-UWB is more suitable for high-speed indoor links. System based on TH show that, in general, it is less robustness against acquisition errors compared with that of DS-UWB.
