Abstract
A multi-carrier communication system () groups subchannels () into different quality-of-signal (QoS) regions (). An unconstrained optimization process () is performed independently for the subchannels () of the different QoS regions () to allocate bit rates and power to the individual subchannels () so that the indicated QoS will result. Coders () partition and error-correction encode source information using encoding schemes matched to the different QoS regions (). A set () of only a few directed QoS partition vectors () direct the unconstrained optimization process () to attempt bit-rate and power allocations on only a few promising groupings of subchannels () and QoS regions (). An iterative process may take place between bit-rate and power allocation on one side and source information coding on the other for different directed QoS partition vectors () to identify the best solution.
