Dispositif de transmission radio et dispositif de reception radio


Radio transmission device and radio reception device


Dispositif de transmission radio susceptible d’améliorer le débit. Le dispositif de transmission radio (100) transmet un premier signal et un second signal qui sont différents l’un de l’autre. Dans le dispositif de transmission radio (100), une unité FFT (103) soumet des premières données à un processus FFT. Une unité d’attribution de sous-porteuses (106) met en corrélation les premières données qui ont été soumises au processus FFT et les secondes données dans des fréquences différentes. Une unité IFFT (107) soumet le signal mis en corrélation à la transformation IFFT. Une unité de traitement de radio transmission (109) transmet le signal qui a été soumis au traitement IFFT, avec une porteuse unique.
There is disclosed a radio transmission device capable of improving the throughput. The radio transmission device (100) transmits a first signal and a second signal which are different from each other. In the radio transmission device (100), an FFT unit (103) subjects first data to an FFT process. A sub-carrier allocation unit (106) maps the first data which has been subjected to the FFT process and the second data into different frequencies. An IFFT unit (107) subjects the mapped signal to the IFFT transform. A transmission radio processing unit (109) transmits the signal which has been subjected to the IFFT processing, with a single carrier.
