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.

Claim (Index 7):
A device for processing information representative of a transmission channel between radio equipment, called a receiver comprising a plurality (r) of antennas and at least one transmitting antenna, and radio equipment, called a transmitter comprising a plurality (t) of transmission antennas and at least one receiving antenna, the number of transmitting antennas (t) being greater than the number of receiving antennas (r), said information comprising a matrix (H) representative of the transmission channel estimated beforehand from at least one received data signal, said device comprising:\n a processor; and a non-transitory computer-readable medium comprising instructions stored thereon, which when executed by the processor configure the device to perform acts comprising: obtaining at least one pair of eigencharacteristics of the product of the conjugate transpose of the channel matrix with the channel matrix (H*H), consisting of non-zero eigenvalues (\u03bb i ) and eigenvectors (ui) associated with said eigenvalues; measuring (\u03c1) a signal to noise ratio in the transmission channel; calculating at least one eigenvalue (\u03bc i ) of a autocorrelation matrix of symbols on transmission, according to a criterion of maximizing a capacity (C) of the transmission channel, from the eigenvalues (\u03bb i ) obtained, arranged in descending order and the measurement (\u03c1) of the signal to noise ratio, according to the following equations: 0 \u2264 p \u2264 argmax m \u2264 r \ue89e m - 1 ( 1 + ( rt \ue89e \ue89e \u03c1 ) - 1 \ue89e \u2211 k \u2264 m \ue89e \u03bb k - 1 ) > ( rt \ue89e \ue89e \u03c1 \ue89e \ue89e \u03bb m ) - 1 \u03bc i = 1 p \ue89e ( 1 + \u2211 j = 1 p \ue89e 1 rt \ue89e \ue89e \u03c1 \ue89e \ue89e \u03bb j ) - 1 rt \ue89e \ue89e \u03c1 \ue89e \ue89e \u03bb i \ue89e \ue89e for \ue89e \ue89e 1 \u2264 i \u2264 p \u03bc i = 0 , for \ue89e \ue89e p < i \u2264 t the non-zero eigenvalue (\u03bc i ) of the autocorrelation matrix being associated with the same eigenvector (u i ) as the eigenvalue (\u03bb i ) of the product of the conjugate transpose of the channel matrix with the channel matrix (H*H);\n transmitting, to the transmitter equipment information representative of said at least one calculated non-zero eigenvalue (\u03bc i ) associated with the eigenvector (u i ).
