Efficient sparse channel estimation based on compressed sensing

摘要

The present invention relates to a method of channel estimation including: - reception of measurements from a transmitter having a plurality of transmit antennas at a receiver having a plurality of receive antennas; characterized in that the method includes: - a first determination of at least one set of angles of departure based on the received measurements, each angle of departure being associated to at least one path of the channel for a radio transmission between the transmitter and the receiver; - a second determination of a plurality of sets of at least one parameter based on the determined set of angles of departure, each set of at least one parameter being associated to a path of the channel for a radio transmission between the transmitter and the receiver.
