Abstract
The present prevent relates to a method of sparsifying a channel using beamforming in a wireless communication system, the method including inserting pilot symbols into resources allocated among resource elements constituting a time-frequency grid; calculating beamforming weights for sparsifying a beamformed time-domain channel; and beamforming frequency-domain channels of a plurality of antennas mapping the pilot symbols by using the beamforming weights.
