  • Method of widely linear turbo-equalization in a multi-user context and for a multi-channel multi-antenna receiver
    Patent number: 9432223
    Abstract: A method of equalizing a signal received by a plurality of antenna elements, the received signal being produced by the transmission of signals by a plurality of transmitters, includes: a step of converting the received signal into the frequency domain; a step of subtracting from the signal an estimate of the intersymbol interference and the interference between users so as to obtain a complex corrective signal; a step of conjoint widely linear filtering of the complex corrective signal and the conjugate complex corrective signal to obtain an equalized signal; a step of converting the equalized corrective signal into the time domain; a step of calculating coefficients of the at least one equalizer filter from the covariance matrix and the pseudo-covariance matrix of the received signal.
