 Pick two maximum length sequences of the same length 2"n" − 1 such that their absolute cross-correlation is less than or equal to 2("n"+2)/2, where "n" is the size of the linear feedback shift register used to generate the maximum length sequence (Gold '67).The set of the 2"n" − 1 exclusive-ors of the two sequences in their various phases (i.e.translated into all relative positions) together with the two maximum length sequences form a set of 2"n" + 1 Gold code sequences.
