Abstract:
Receiver and method for receiving one or more RF signals, the RF signals comprising a component relative to a direct propagation path and, depending on a propagation environment, one or more additional components relative to reflected propagation paths, the receiver comprising a calculation circuit configured to: compute at least a first correlation function (310) between the received signal and at least a replica of a RF signal generated at the receiver, and for at least an output of said first correlation function: perform a cepstrum transform (410), search for one or more reflected propagation paths from the output of the cepstrum transform (411), and when reflected propagation paths are detected, determine the associated propagation characteristics (412), and remove the contribution of the detected reflected propagation paths from one of the received signal or the output of the first correlation function.
