Abstract
A method for processing information representative of a transmission channel between a radio transmitter and a radio receiver. The information includes a matrix representative of the transmission channel. The method includes obtaining at least one pair of eigencharacteristics of the product of the conjugate transpose of the channel matrix with the channel matrix, consisting of non-zero eigenvalues; obtaining a measurement of a signal to noise ratio in the transmission channel; calculating at least one eigenvalue of an autocorrelation matrix of the symbols on transmission, according to a criterion of maximizing a capacity of the transmission channel, from the eigenvalues obtained; and transmitting to the radio transmitter information representative of the at least one calculated non-zero eigenvalue associated with the eigenvector.
