Hadamard transforms of three-term sequences
Guang Gong, Solomon W. Golomb · IEEE Transactions on Information Theory · 1999
Certain three-term sequences of period 2/sup n/-l are conjectured to have the two-level autocorrelation property. In this note, a formula involving Hadamard transforms of three-term sequences is presented. Its validity has been verified by computer on the range of 5/spl les/n/spl les/23.
