Abstract: Method and device for estimating the time-of-arrival of a received signal y(t), said method comprising the step of: generating a plurality of frequency-domain samples from the received signal y(t); estimating a correlation matrix (Formula I) from said plurality of frequency-domain samples; from said correlation matrix (Formula I), calculating a signal energy distribution with respect to different propagation delays; finding a delay value (Formula II) at which said signal energy distribution exceeds a certain threshold Pth, said delay value representing the time-of-arrival estimation.
