Patent ID: 8867658

Claim:
A multicarrier-signal transmitting apparatus comprising: a rotation-amount setting unit configured to set a phase rotation amount for each subcarrier of a plurality of subcarrier groups, wherein the phase rotation amount being set with a setting selected from at least two settings, a first setting of the at least two settings being that the phase rotation amount is set for a first subcarrier group set which includes a plurality of continuous subcarrier groups, the first subcarrier group sets being in the plurality of subcarrier groups, a second setting of the at least two settings being that the phase rotation amount is set for a second subcarrier group set which includes a plurality of continuous subcarrier groups, the second subcarrier group sets being in the plurality of subcarrier groups, and the number of the continuous subcarrier groups included in the first subcarrier group set is different from the number of the continuous subcarrier groups included in the second subcarrier group set; and a phase rotator configured to add, based on the phase rotation amount, a phase rotation to reference signals and a data signal of the each subcarrier of the plurality of subcarrier groups.
