Abstract :
A novel threshold selection technique is proposed in this paper to estimate the time of arrival (TOA) in impulse radio ultra-wide bandwidth (IR-UWB) systems. This technique can generate a threshold through an iterative process without any a-priori knowledge for the threshold-based TOA estimation. Monte Carlo simulations are used to confirm the validity of our threshold selection technique. The results show that the technique we propose is able to achieve comparable performance to a sub-optimal threshold comparison (TC) approach which needs perfect estimations of certain channel parameters.
