Optical orthogonal codes

Webn>>w>( ). Various one-dimensional optical orthogonal code design schemes for constant weight have been proposed in literature. These schemes can design single set of optical orthogonal codes corresponding to specific values of code parameters (n,w, ). The sets of 1-DUOC with variable or multi-weight parameter have larger cardinality than that of Weboptical orthogonal codes enables a large number of asynchronous users to transmit information efficiently and reliably. The lack of a network synchronization requirement enhances the flexibility of the system. In [3] Let (n, w, λa, λc) be positive integers. An (n, w, λa, λc) optical orthogonal code, or briefly a (n, w, λa, λc) -
