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

  • estimating characteristics of a plurality of transmission channels available for data transmission;

    segregating the plurality of transmission channels into one or more groups of transmission channels, each group being associated with a particular coding and modulation scheme and a particular threshold used to select transmission channels in the respective group for use for data transmission; and

    for each group of transmission channels, selecting one or more transmission channels for use for data transmission based on the estimated channel characteristics and the particular threshold associated with the respective group, allocating total transmit power available for the group amongst the one or more selected transmission channels in accordance with a defined allocation scheme, coding and modulating data for the one or more selected transmission channels in accordance with the particular coding and modulation scheme associated with the respective group, and transmitting the coded and modulated data for each selected transmission channel based on the allocated transmit power.
