Patent ID: 7269209

Claim:
A method, in a tone generation module, for assigning bits in a plurality of frames to a plurality of tones in a multitone transmission, wherein the bits in each frame are assigned to the plurality of tones, comprising: (a) receiving, in an assignment module, a first unique tone order mapping sequence in a set of unique tone order mapping sequences, wherein the first unique tone order mapping sequence defines a first order of the plurality of tones; (b) assigning bits in a first frame to the plurality of tones according to the first unique tone order mapping sequence; (c) receiving, in the assignment module, a second unique tone order mapping sequence in the set of unique tone order mapping sequences, wherein the second unique tone order mapping sequence defines a second order of the plurality of tones; (d) assigning bits in a second frame to the plurality of tones according to the second unique tone order mapping sequence; and (e) repeating steps (c) and (d) for each unique tone order mapping sequence in the set of unique tone order mapping sequences, wherein the set of unique tone order mapping sequences includes one mapping sequence for each possible permutation of tone ordering, wherein the number of permutations is based on the number of tones being used for the transmission.
