Claim Text:
1. A received signal equalization method using at least one equalizer filter to equalize a signal received by a plurality of antenna elements, said received signal being produced by a transmission of signals by a plurality of transmitters, said method comprising: converting the received signal into a frequency domain to obtain a frequency domain signal, subtracting from said frequency domain signal an estimate of an intersymbol interference and an interference between users to obtain a complex corrective signal, conjoint widely linear filtering said complex corrective signal and a conjugate of the complex corrective signal to obtain an equalized signal, converting the equalized signal into a time domain, calculating a covariance matrix of the received signal, calculating a pseudo-covariance matrix of the received signal at least from a pseudo-covariance of symbols of said transmitted signals, and calculating coefficients of said at least one equalizer filter from the covariance matrix and the pseudo-covariance matrix of the received signal.
