1. A method of limiting noise in a plurality of signals transmitted on a transmission channel, comprising:
preprocessing the plurality of signals, said preprocessing including multiplying said signals with first coefficients; receiving from the transmission channel the plurality of preprocessed signals in a multi-reception receiver having a plurality of reception ports, each reception port receiving one of the plurality of preprocessed signals, decorrelating the noise present in the received signals by the receiver, wherein decorrelating comprises multiplying the noise by second coefficients varying with time or with frequency, or with time and frequency; and wherein said first coefficients are linked with said second coefficients in order to pre-compensate for an effect of said second coefficients on a useful part of the received signals.
