Structure of adaptive multiple antennas and communication device and method using adaptive multiple antennae
The present invention relates to communication using multiple antennas, and more particularly, to an apparatus and method for adaptively adjusting, based on a channel environment, an interval and direction of multiple antennas each of a transmitter and a receiver. A communication method according to the present invention may include verifying information about a channel state based on a pilot signal transmitted for each antenna of a transmitter, adjusting intervals among antennas of a receiver based on the information about a channel state, calculating transmission capacity values according to the adjusted intervals among antennas, and setting an antenna to an antenna interval corresponding to a transmission capacity having a highest value among the transmission capacity values calculated.
