The patent application relates to a method 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 a support set indicating a set of first indices of non-zero communication signal coefficients from the channel matrix and the receive signal, determining an estimate of the sparse communication signal upon the basis of the support set, the channel matrix and the receive signal, determining second indices of communication signal coefficients which are not indicated by the support set, and determining 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.

Method for recovering a sparse communication signal from a receive signal

A wireless receiver being capable of determining its velocity with respect to a number of wireless transmitters is provided. The wireless receiver includes a communication interface for receiving a number of carrier signals originating from the number of wireless transmitters, and a processor being configured to determine a number of carrier phases of the carrier signals at two different time instants, to determine a number of carrier phase differences from the determined number of carrier phases for each carrier signal between the two different time instants, to determine a location matrix indicating a geometric relationship between a location of the wireless receiver and a number of locations of the number of transmitters, and to determine the velocity of the wireless receiver upon the basis of the number of carrier phase differences and the location matrix.
