ABSTRACT:
A method is provided for processing a signal emanating from a multi-path transmission medium. Echoes of the signal that is received are detected, and a rejection processing is performed. The rejection processing includes estimating the cross-correlation between temporally neighboring echoes, and if this cross-correlation satisfies a test, rejecting the one of the two neighboring echoes that exhibits the lower energy. Also provided is a rake receiver that can perform such a method.
