摘要
Modulation information is efficiently notified to a communicating destination. Provided are a first modulation information determining section 1 that determines first modulation information for each subcarrier or each subcarrier group with grouped subcarriers based on the propagation path information and bitmap information determined from modulation information, a data transform section 2 that transforms the first modulation information into a different data space, a second modulation information determining section 3 that compresses the transformed data to determine second modulation information to be notified to a communicating destination, an inverse data transform section 4 that inversely transforms the second modulation information into an original data space, and a third modulation information determining section 5 that determines third modulation information for each subcarrier or each subcarrier group with grouped subcarriers based on the inversely-transformed data and the bitmap information.
