| Title of Invention | "RADIO TRANSMISSION SYSTEM COMPRISING TRANSMITTER APPARATUS AND RECEIVER APPARATUS AND RADIO TRANSMISSION METHOD" |
|---|---|
| Abstract | A radio transmission system for radio transmission of information between a transmission station and a reception station by using an orthogonal frequency code-division multiplexing transmission method for parallel transmission of the same information by a plurality of sub-carriers. The system includes spread ratio variable control transmission means for parallel conversion of information channel-encoded at the transmission station, according to a symbol transmitted simultaneously, and spreading the series of the parallelized symbols by the spread code series of the specified spread ratio at least in one of the frequency direction and the time direction. |
