METHOD FOR RECOVERING A SPARSE COMMUNICATION SIGNAL FROM A RECEIVE SIGNAL

摘要

The invention relates to a method (100) for recovering a sparse communication signal from a receive signal, the receive signal being a channel output version of the sparse communication signal, the channel comprising channel coefficients being arranged to form a channel matrix, the method comprising determining (101) a support set indicating a set of first indices of non-zero communication signal coefficients from the channel matrix and the receive signal, determining (103) an estimate of the sparse communication signal upon the basis of the support set, the channel matrix and the receive signal, determining (105) second indices of communication signal coefficients which are not indicated by the support set, and determining (107) the sparse communication signal upon the basis of the support set, the estimate of the sparse communication signal, the second indices and the channel matrix.
