1. A method comprising:

  • selecting, from a set of bits, a bit designated by an index;

    assigning the selected bit to one of N carrier frequencies that does not yet have a bit assigned thereto;

    incrementing the index, and repeating the selecting and assigning acts, until each of the N carrier frequencies has a bit assigned to it;

    for each of the N carrier frequencies, assigning a second bit thereto, wherein the newly assigned bit is designated by an index value equal to the sum of the index of the bit already assigned thereto and an integer multiple of N;

    wherein, for each of the N carrier frequencies, the bits assigned thereto at least partially jointly determine a symbol to be modulated upon the carrier frequency.
