Abstract :
In this paper, we discuss the design of STTC for TH-UWB-IR systems with different modulations. The performances of these STTC schemes are evaluated under various conditions such as multipath and multiuser through simulations. The results show that STTC-UWB with PPM can achieve much better performance than the schemes employing PAM and biorthogonal modulation. Furthermore, we find the performance degrades when the number of users increases
