Low Complexity Frequency Domain TOA Estimation for IR-UWB Communications
Mònica Navarro, Simon Prior, Montse Nájar · IEEE Vehicular Technology Conference · 2006
This paper addresses the problem of TOA estimation for ranging applications in IR-UWB. It considers a low complexity frequency-domain approach for the estimation of the TOA that allows sub-Nyquist sampling rate receivers. Two diversity schemes are investigated in combination with the TOA estimation algorithm and are evaluated over realistic channel models, yielding accurate ranging estimation.
