Efficient sparse channel estimation based on compressed sensing

摘要

The present invention is a method of channel estimation comprising receiving at a receiver having a plurality of receiving antennas a measurement from a transmitter having a plurality of transmitting antennas, the method comprising: A first operation for determining at least one set of emission angles based on, each emission angle being associated with at least one path of a channel of wireless transmission between a transmitter and a receiver A second operation for determining a plurality of sets of at least one parameter based on the set of operation and the determined launch angle, wherein each set of at least one parameter is between the transmitter and the receiver. And a second operation associated with a path of a channel of wireless transmission.
