1. A multicarrier-signal transmitting apparatus comprising:
a rotation-amount setting unit configured to and/or programmed 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 among at least three settings, a first setting of said at least three settings being that the phase rotation amount is set for first subcarrier group sets, wherein each set of said first subcarrier group sets includes a plurality of continuous subcarrier groups, the first subcarrier group sets being in the plurality of subcarrier groups, a second setting of said at least three settings being that the phase rotation amount is set for second subcarrier group sets, wherein each set of said second subcarrier group sets includes a plurality of continuous subcarrier groups, the second subcarrier group sets being in the plurality of subcarrier groups, a third setting of said at least three settings being that the phase rotation amount is set for third subcarrier group sets, wherein each set of said third subcarrier group sets includes a plurality of continuous subcarrier groups, the third subcarrier group sets being in the plurality of subcarrier groups, and each number of the continuous subcarrier groups included in each subcarrier group set is different from each other; and a phase rotator configured to and/or programmed 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. |
