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

摘要

The multiple carrier transmission system transmits channel information between two transceivers using several subcarriers modulated with symbols. Each symbol represents several bits. Each transceiver has a receiver and a transmitter. A fixed maximum value is determined for the number of bits for each symbol. The system determines the bit capacity per symbol of each of the subcarriers and increases the number of bits represented by a symbol transmitted over those subcarriers having a capacity less than the fixed maximum value to the maximum value by the addition of channel coding bits.
