ABSTRACT:
In order to improve system throughput in a radio transmitting apparatus of a multicarrier system in which transmission is performed simultaneously to a plurality of receiving stations using subcarriers, subcarriers are divided into blocks, a receiving station is selected on a block unit basis, and the number of subcarriers per block is varied adaptively for each receiving station based on the propagation environment of that receiving station.
