Abstract
The present invention relates to a multi-antenna channel estimation apparatus and method for performing beamforming in a communication system in which only single channel estimation is possible, and relates to a channel estimation apparatus and method for beamforming in which the transmitter generates pilot signals based on the Zadoff-Chu sequence and transmits the generated pilot signals to the receiver, the receiver estimates a channel based on the pilot signal, and feeds back information for beamforming to the transmitter based on the estimated channel information, and it is configured to enable beamforming by converting and setting the signal phase for each antenna according to the feedback received from the transmitter.
