Abstract :
A construction of 64-QAM Golay complementary sequences was proposed by Lee and Golomb, where three QPSK Golay-Davis-Jedwab complementary sequences (GDJ sequences, or standard Golay sequences) related by a pair of offsets were combined to form each 64-QAM Golay sequence. Feasible offset pairs were given as first order generalized Boolean functions in algebraic normal form. New offset pairs were described in a conjecture of Li, leading to new 64-QAM Golay complementary sequences. The proof of the conjecture is presented.
