1. A method comprising:
receiving a training signal over a set of active frequencies
estimating a number of radio propagation paths and a fading coefficient of each of the radio propagation paths based on a channel frequency response value estimated from the received training signal;
reconstructing the channel frequency response value for a set of null frequencies based on the number of radio propagation paths and the fading coefficient of each of the radio propagation paths;
estimating a time-of-arrival parameter based on the reconstructed channel frequency response value; and
performing a localization procedure based on the estimated time-of-arrival parameter.
