RADIO TRANSMISSION DEVICE, CONTROL DEVICE, RADIO COMMUNICATION SYSTEM, AND COMMUNICATION METHOD |
摘要 |
A radio transmission device includes: a time-to-frequency converter that converts a time domain signal into a plurality of frequency signals; a subcarrier allocator that segments the plurality of frequency signals into a plurality of blocks, and allocates the plurality of frequency signals included in each of the plurality of blocks onto sequential subcarriers; a transmission power adjustor that adjusts a transmission power of a transmission signal including the plurality of subcarriers; and a controller that controls the subcarrier allocator and the transmission power adjustor so that the number of frequency signals included in one block increases as the transmission power increases. |
