Abstract
A method for transmitting data in a frequency selective communication channel in provided. The method comprises: parsing data to be transmitted into a plurality of data fields; assigning the data from each data field into a corresponding one of a plurality of sub-channels; modulating the data from each of the plurality of sub-channels into a corresponding one of a plurality of sub-bands, the plurality of sub-bands having spaced apart center frequencies; and concurrently transmitting the data from the plurality of sub-bands onto the channel.
