1. A method for cancelling interferences of a received MIMO RF signal, wherein said method comprises: a step of receiving a MIMO RF signal y; an initial step of obtaining, from said received signal y, at least one data representative of a decoded signal, called at least one decoded data; computing said at least one decoded data as a function of at least one predetermined criterion, delivering feedback data and a feedback decision depending on a cyclic redundancy check of the decoded data, comprising: a step of obtaining at least two cyclic redundancy checks from said decoded data; a step of obtaining a criterion to applied to said at least two cyclic redundancy checks, a step of comparing said at least two cyclic redundancy checks; and a step deciding whether feedback data are delivered for further processing as a function of said step of comparing and said criterion, delivering the feedback decision; and, as a function of said feedback decision, a predetermined number of iterations of the following steps: constructing a set of feedback symbols from said feedback data; a step of obtaining, from said set of feedback symbols, at least one data representative of a feedback decoded signal, called feedback decoded data; computing said at least one feedback decoded data as a function of said at least one predetermined criterion, delivering said feedback data.
