ABSTRACT:
A method is used that substantially simultaneously trellis encodes data to be modulated onto multiple tones. The embodiments of the present invention comprise the steps of: (a) using a first input operand comprising state bits for a first trellis stage; (b) using a second input operand comprising a plurality of input data bits; and (c) generating an output comprising output data bits and output state bits from a first or later trellis stage.
