| 发明名称 | Data retransmission request device, a data transmitter, and a data retransmission method for multi-tone systems | ||
| 摘要 | In a multi-tone data transmission system, data are modulated on a set of M tones for being transmitted between a transmitter and a receiver. The data retransmission request device in such system is adapted to request retransmission of a data transmission unit that is hierarchically modulated at a particular hierarchical level and that is modulated on a particular group of N tones, N being a positive integer value greater than one and smaller than or equal to M. | ||
