Several classes of (2m−1,w,2) optical orthogonal codes Original Research Article

Optical orthogonal codes have applications in optical code-division multiple access communication systems and other wide band code-division multiple environments. They can also be used to construct protocol sequences for multiuser collision channel without feedback, and constant weight codes for error detection and correction. In this paper, we construct four classes of (2m−1,w,2) cyclotomic optical orthogonal codes, where w∈{5,9} or w⩾11 is any prime having primitive root 2, and therefore the corresponding classes of binary constant-weight cyclic codes.
