Method to provide cross-talk cancellation
First Claim
1. A method to provide cross-talk cancellation in a multiple input multiple output system comprising a plurality of outputs (OUT1, OUT2, . . . , OUTn), said method comprises a step of executing for a first signal (Si) a cross-talk cancellation, characterized in that said method further comprises determining during a first phase and according to a heuristic model, for said first signal (Si) to be transmitted to a first output (OUTi) of said plurality of outputs (OUT1, OUT2, . . . , OUTn), at least one dominant interfering tone (D) of at least one second signal (Sj) to be transmitted to a second output (OUTj) of said plurality of outputs (OUT1, OUT2, . . . , OUTn), said at least one dominant interfering tone (D) being a tone of said at least one second signal (Sj) that would generate cross-talk upon said first signal (Si) when being transmitted to said first output (OUTi);
- and executing said step of cross-talk cancellation for said first signal (Si) during a second phase for said at least one determined dominant interfering tone (D) of said second signal (Sj).

Abstract
A method to provide cross-talk cancellation in a multiple input multiple output system that comprises a plurality of outputs is described. The method comprises a step determining during a first phase and according to a heuristic model, for a first signal to be transmitted to a first output of the plurality of outputs at least one dominant interfering tone of at least one second signal to be transmitted to a second output of the plurality of outputs. The at least one dominant interfering tone is in fact a tone of at least one second signal that would generate cross-talk upon the first signal when it would be transmitted to the first output. The method further comprises a step of executing a step of partial cross-talk cancellation for the first signal during a second phase for the one or more determined dominant interfering tones associated to one or another second signal.
