A method for the reception of a data signal which, before being sent, has undergone a linear precoding by means of a unitary preceding matrix, and a channel coding, comprises at least one iteration to improve an estimation of the received signal, as a function of the received signal and of a preceding estimation of the received signal. This iteration comprises the following steps: the estimation of the interference due especially to the linear precoding and affecting the received signal, as a function of the preceding estimation, so as to obtain an estimated interference; the subtraction of the estimated interference from the preliminarily filtered and de-precoded received signal, so as to obtain an improved signal; the equalization of the improved signal, delivering an equalized signal; the estimation of the received signal, delivering an estimation of the received signal.
