Method and apparatus for processing data for transmission in a multi-channel communication system using selective channel inversion

A method for processing data for transmission over multiple transmission channels in a multi-channel communication system, comprising:

• determining characteristics of a plurality of transmission channels available for data transmission;
• selecting one or more available transmission channels based on the determined characteristics and a metric;
• coding data for all selected transmission channels based on a particular common coding scheme to provide coded data selected for the transmission channels that were selected;
• and
• modulating the coded data for all selected transmission channels based on a particular modulation scheme to provide modulation symbols.

A method for transmitting data over multiple transmission channels in a multi-channel communication system, comprising:

• determining characteristics of each of a plurality of transmission channels available for use for data transmission;
• segregating the plurality of available transmission channels into one or more groups;
• coding and modulating data for selected ones of the available transmission channels in each group to provide modulation symbols;
• weighting modulation symbols for each selected transmission channel in each group based on a respective weight indicative of a transmit power level for the selected transmission channel and derived based in part on the determined characteristics of the selected transmission channel;
• and
• transmitting the weighted modulation symbols on the selected transmission channels.
