New families of binary sequences with optimal three-level autocorrelation
Cunsheng Ding, Tor Helleseth, H.M. Martinsen · IEEE Transactions on Information Theory · 2001
In this correspondence we give several new families of binary sequences of period N with optimal three-level autocorrelation, where N/spl equiv/2 (mod 4). These sequences are either balanced or almost balanced. Our construction is based on cyclotomy.
