Abstract

L'invention concerne un procédé et un appareil d'émission et de réception de signal. En particulier, l'invention concerne un procédé et un appareil d'émission et de réception de signal permettant d'augmenter un débit de transfert de données. Selon le procédé de l'invention, les symboles sont mappés selon une pluaralité de procédés de mappage de symboles dans lesquels les espaces situés entre des symboles voisins sont identiques. Les données de symboles mappés sont modulées, puis transmises. Ainsi, il est possible d'augmenter le débit de transfert de données en fonction d'un gain SNR (rapport signal/bruit) et d'améliorer la performance d'émission/réception de signal du système d'émission/réception de l'invention. Lorsqu'un procédé de multimappage ou de multicodage est utilisé, le rapport existant entre un SNR nécessaire et un débit de données de transfert est ajusté afin d'améliorer l'efficacité de transmission.
