WebApr 15, 1998 · The study of optical orthogonal codes is motivated by an application in a code-division multiple-access fiber optical channel which requires binary sequences with good correlation properties. In this paper, some combinatorial constructions for optimal ( v , k , 1) optical orthogonal codes are developed. WebAn optical orthogonal code (OOC) is a family of (0,1) sequences with good auto- and cross-correlation properties, i.e the autocorrelation of each sequence exhibits the `thumbtack' shape and the cross correlation between any two sequences remains low throughout. The use of optical orthogonal codes enables a large number of asynchronous users to ... WebStrict optical orthogonal codes are presented for purely asynchronous optical code-division multiple-access (CDMA) applications. The proposed code can strictly guarantee the peaks of its cross-correlation functions and the sidelobes of any of its autocorrelation functions to have a value of 1 in purely asynchronous data communications. incompatibility\u0027s lr
