摘要
A method to discriminate a real echo peak from an aliased echo peak comprises: computing ' a correlation between N samples of a digital data and a copy of the same N samples delayed by a time delay Δ1,0 to obtain a first correlation result, time delay Δ1,0 being equal to a time interval T between a first and a second distinct power peaks of an estimated channel impulse response, the first peak being the highest power peak within the temporal window, and/or computing - a correlation between the N samples and a copy of the same N samples delayed by a time delay TIFFT- Δ1,0 to obtain a second correlation result, and deciding whether the second peak is a real echo peak or an aliased echo peak based on the first and/or second correlation results.
