Abstract

In our previous work [1], we have analysed Multiuser Interference (MUI) by considering synchronous and asynchronous transmission under multiuser case for DS-CDMA based OFDM system. In [1] we have considered MUI at receiver from N-1 active users. In this paper we have examine MUI by considering packet based transmission with Impulse radio. In this situation MUI is generated due to collision of UWB pulses, which are used to define single bit under UWB transmission. This type of interference will take place in UWB based network due to organization of information bits into packets by higher layers. Here we have considered the TH-PAM and TH-PPM based Impulse radio systems for evaluating MUI.
