Multicarrier-signal receiving apparatus and multicarrier-signal transmitting apparatus

A multicarrier-signal transmitting method comprising:

• setting 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
• adding, 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.

A non-transitory computer-readable medium having instructions stored thereon, such that when the instructions are read and executed by a processor, the processor is configured to perform the steps of:

• setting 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
• adding, 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.
