METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING SIGNAL IN OFDM SYSTEM |
| 摘要 |
In an orthogonal frequency division multiplexing (OFDM) wireless communication system, by modulating a phase of a symbol signal of source data to transmit and by performing constellation mapping of additional data having a coded channel and a signal having a modulated phase, a transmitting signal in which the additional data and the signal having a modulated phase are coupled is generated and transmitted. |

1. A transmitting method in an orthogonal frequency division multiplexing (OFDM) wireless communication system, the transmitting method comprising:
generating a symbol signal of source data to transmit; performing inverse fast Fourier transform (IFFT) processing of the symbol signal; modulating a phase of the IFFT processed signal; generating a transmitting signal in which additional data and the signal having a modulated phase are coupled by performing constellation mapping of the additional data having a coded channel and the signal having a modulated phase; and transmitting the transmitting signal. |
