COMMUNICATION DEVICE AND COMMUNICATION SYSTEM |
| 摘要 |
A transmitter includes a generation section that generates a baseband OFDM signal based on transmission data, and a transmission section that transmits a communication signal that is based on a real-part signal that is obtained by removing an imaginary-part signal from the baseband OFDM signal. In the baseband OFDM signal, the data signal including the transmission data is superimposed on subcarriers that are given numbers equal to or less than N/2−1, and the data signal is not superimposed on subcarriers that are given numbers more than N/2−1, where N (N is an integer) subcarriers included in the baseband OFDM signal are numbered by integers from 0 to N−1 in ascending order with respect to the center frequency of each subcarrier. |

1. A communication device comprising:
a generation section configured to generate a baseband OFDM signal based on transmission data; and a transmission section configured to transmit a communication signal that is based on a real-part signal that is obtained by removing an imaginary-part signal from said baseband OFDM signal, wherein in said baseband OFDM signal, a data signal including said transmission data is superimposed on a subcarrier that is given a number equal to or less than N/2−1, and a data signal is not superimposed on a subcarrier that is given a number more than N/2−1, where N (N is an integer) subcarriers included in said baseband OFDM signal is numbered by integers from 0 to N−1 in ascending order with respect to the center frequency of each subcarrier. |
