Improvements in, or relating to, multi-carrier transmission systems

(57) What summary book invention offers is the multiplex carrier transmission system which transmits channel information between two transceivers using two or more subcarriers, for example, a DMT system. The feature of this system is used, in order that each subcarrier or a sign may have a parameter about it and those transceivers' may transmit the above-mentioned channel information as a continuous n group. Each of this n group has the information about the adjacent number of subcarriers and actual value of a parameter with the same value as the above-mentioned parameter. The parameter which can have two or more discrete values is made with a bit loading value or an OAM array identifier.
