This paper analyzes the receiver's ability to differentiate between multiple users in ultra-wideband (UWB) impulse radio (IR) during the initial synchronization phase after a cold start, i.e., when the receiver is not yet synchronized with the user of interest. Because of multiple access interference (MAI), the receiver may combine the pulses of other users in a partially coherent way. In this...

Asymptotical Analysis of Timing Imperfections in UWB Receivers

Merz, Roman ; Botteron, Cyril ; Farine, Pierre-André ; Farserotu, John

In: 2nd IEEE International Conference on Circuits and Systems for Communications (ICCSC’2004), 2004, vol. 2, p. 1-4

In this paper, a model is proposed to analyze the influence of timing imperfections on ultra-wide bandwith (UWB) time-hopping spread-spectrum (TH-SS) signaling schemes, where N pulses are coherently added to increase the received signal-to-noise ratio (SNR). Based on this model, we derive asymptotical (valid for large N) expressions for the received signal after pulse summation and matched...
