Abstract (en)

A method for selecting a subset of a plurality of inputs of a Multiple-Input-Single-Output, MISO, system, the MISO system comprising: the plurality of inputs X<sub>i</sub>, wherein i = 1, 2, ..., n, and a single output Y. The method comprises steps in a following order:1) calculating a coherence value representing a coherence level between each of the plurality of inputs X<sub>i</sub> and the single output Y;2) among the plurality of inputs X<sub>i</sub>, selecting an input having a largest coherence value;3) creating a remaining group of inputs, wherein the remaining group of inputs consists all inputs of the plurality of inputs X<sub>i</sub> except the previously selected input(s);4) for each input of the remaining group of inputs,generating a corresponding conditioned input by conditioning the input;5) for each conditioned input,calculating a partial coherence value representing a coherence level between the conditioned input and the single output Y;6) among the remaining group of inputs, selecting an input corresponding to a conditioned input having a largest partial coherence value.
