Abstract:
A radio transmitter of the present invention includes a scheduler for assigning a communication time or a communication frequency to each radio receiver based on quality information of a received signal transmitted by the radio receiver, a transmission circuit controller for transmitting either a frequency diversity region or a multiuser diversity region to be selected with respect to each chunk, and a transmission circuit for applying different delay times to signals of a plurality of transmission antennas based on a transmission result of the transmission circuit controller.
