Abstract:
1. A multicarrier communication apparatus comprising: a superimposing section that superimposes transmission symbols with a plurality of subcarrier groups, each of the plurality of subcarrier groups including a plurality of subcarriers; a control section that controls a first combined transmission power of each of the plurality of subcarrier groups on which the transmission symbols are superimposed; and a transmission section that transmits a multicarrier signal obtained by controlling the first combined transmission power of each of the plurality of subcarrier groups, wherein: the control section increases or decreases, by a power control amount, a transmission power of each subcarrier of the plurality of subcarrier groups such that each of the plurality of subcarrier groups has the same second combined transmission power, the power control amount being a value obtained by dividing a difference between a combined received power for each of the plurality of subcarrier groups at a remote communication station and a desired target received power by a number of subcarriers included in each of the plurality of subcarrier groups.
