DEVICE AND METHOD FOR PERFORMING COMMUNICATION IN A VARIABLE BAND |
摘要 |
<p>A transmitter according to the present invention includes a mapping unit configured to convert transmitted data into data pieces associated with individual subcarriers, an inverse Fourier transform unit configured to convert the data pieces into a time-series signal, and a symbol generation unit configured to generate symbols for radio transmission from the time-series signal. The mapping unit associates the transmitted data with subcarriers different from predefined multiple subcarriers arranged at even intervals on a frequency axis. A demapping unit of a receiver according to the present invention supplies data comprising the data pieces associated with the subcarriers different from the predefined multiple subcarriers arranged at even intervals on a frequency axis as the data for restoration.</p> |
