摘要：
The energy detection(ED) receiver is a practical solution for time of arrival (TOA) estimation in ultra wideband (UWB) ranging, Nevertheless, this method is vulnerable to the interference of noise and other wireless systems. In the study, we propose a novel method based independent component analysis(ICA) to mitigate the interference. This method can separate various kinds of source signals, according to the principle of these source signals statistical independence, then we estimate TOA from the extracted UWB signals. Simulation results show that this method can achieve an accurate TOA estimation for interference suppression in IR-UWB systems.
