ABSTRACT:
A device includes a receiver including an estimation block for estimating the impulse response of the transmission channel and a transformation block. The transformation block may include a preprocessing block for determining a phase minimum transformed impulse response corresponding to a transformed channel based upon the estimated impulse response of the transmission channel, and a filter for filtering the signal received. This makes it possible to retain equality between the autocorrelation of the signal received and the autocorrelation of the filtered signal. Further, the receiver may include an equalizer for applying an equalization processing operation to the filtered signal while taking account of the transformed impulse response.
