Document Type and Number:
Japanese Patent JP5425984
Kind Code:
B2
Abstract:
Provided is a radio transmission device (100) which can flexibly cope with a request for assuring an error ratio feature during a high transmission rate, a request for increasing a cell coverage, or the like. The radio transmission device (100) includes a first subcarrier modulation unit (104) which forms a first subcarrier modulation signal obtained by converting a plurality of modulation signals into a frequency region; a second subcarrier modulation unit (105) which forms a second subcarrier modulation signal obtained by parallel conversion of a plurality of signals; an IFFT unit (111) which forms an OFDM signal by performing inverse Fourier transform on the first and the second subcarrier modulation signal; and a subcarrier mapping unit (110) which controls allocation of the first and the second subcarrier modulation signals.
