ABSTRACT:
Effective throughput is enhanced by minimizing a transmission amount of modulation information per frame.A storage part storing information indicating an adaptive modulation level of a modulation parameter, a difference information output part that generates difference information with one bit indicating a difference between the adaptive modulation level of a modulation parameter used for adaptive modulation in a previous frame and that of a modulation parameter used for adaptive modulation in a current frame, and a frame generation part generating a frame using the difference information as modulation information to notify a receiving side of the modulation parameter used for adaptive modulation of a subcarrier or subcarrier group in the current frame, are provided.
