<p><P>PROBLEM TO BE SOLVED: To provide a subscriber line transmission system which is capable of taking TCM Cross-talk measures by partially changing software in accordance with hardware that adopts a standard scheme, without considerable difference from the standard scheme. <P>SOLUTION: An ADSL system for performing TEQ and FEQ coefficient training includes a means for performing the coefficient training by using a generated synchronization symbol (S) by rotating a phase of each carrier, other than a pilot tone, at 180°after FFT so as to provide the same state as receiving the synchronization symbol (S) if an inverse synchronization symbol (I) is received at a receiving side. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
