Multicarrier-signal receiving apparatus and multicarrier-signal transmitting apparatus

摘要

A multicarrier-signal transmitting apparatus sets 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. The settings being phase rotation amounts for subcarrier groups which each include a plurality of continuous subcarrier groups where each number of the continuous subcarrier groups included in each subcarrier group set is different from each other. Also, the multicarrier-signal transmitting apparatus adds, based on the phase rotation amount, a phase rotation to reference signals and a data signal of each subcarrier of the plurality of subcarrier groups.

主权项

1. A multicarrier-signal transmitting apparatus comprising:
a rotation-amount setting unit configured to 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 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.
