Abstract
A system and method for modifying symbol duration for the efficient transmission of information in a time duplex noise environment is disclosed. In a simplified embodiment, the system modifies the length of Discrete MultiTone (DMT) symbols, thereby providing a system wherein a first half of the DMT symbols are transmitted entirely during a period in which there is far end crosstalk (FEXT) noise, and a second half of the DMT symbols are transmitted entirely during a period in which there is near end crosstalk (NEXT) noise. Preferably, the duration of each DMT symbol is selected to be 0.25 ms such that exactly ten DMT symbols fall within a time duplex period of 2.5 ms. As such, during a FEXT period, exactly five DMT symbols are transmitted, and during a NEXT period, exactly five DMT symbols are transmitted. Therefore, in each TTR period, an additional DMT symbol, with modified length, is transmitted during the FEXT period, during which information is transmitted at a high bit rate.
