Claim 12:
13. The receiver device according to claim 12, the processing circuitry being further configured to determine a set of submatrices comprising all the submatrices in the projection matrix;
determine an interference cancelation signal to be equal to the received signal;
a) project the interference cancelation signal onto each column of the submatrices of the set of submatrices so as to obtain a set of projections,
b) select a column of the projection matrix with a largest projection in the set of projections,
c) add the selected column to a subset of the columns of the projection matrix,
d) cancel the selected column from the interference cancelation signal so as to obtain an updated interference cancelation signal,
e) remove the submatrix comprising the selected column from the set of submatrices;

repeat a) to e) until the set of submatrices is empty and output the subset of the columns of the projection matrix in c).
