A method for receiving a signal, includes a useful signal, interfering signals and noise, and for suppressing interfering signals in a multi-channel receiver, comprising steps of: (a) reception, frequency transposition and digital conversion of the received signal; (b) estimation of a correlation matrix of the received signals; (c) estimation of the variance of the noise; (d) initial estimation of the arrival directions of the useful and interfering signals; (e) initialization of the powers of the useful and interfering signals; (f) iterative computation: of the current directional vectors of the useful and interfering signal; of the powers of the useful and interfering signals; of the amplitude/phase errors of assumed directional vectors with respect to the current directional vectors; and of the arrival directions of the useful and interfering signals; (i) suppression of the interfering signals from the signal received in step (a).
