A (v,k,p) optical orthogonal code ~ is a family of (0,1)-sequences of length v and weight k satisfying the following two properties: (1)~o<.,<.v\_lXtX,+i<~p, for any x = (Xo, x ~ ..... x ~\_ ~ ) e ~ and any integer i ~ 0 (rood v); (2) 5~ o ~, .< ~-~ x~ y, + ~ ~< p, for any x ~ y in ~ and any integer

## Abstract Variable‐weight optical orthogonal code (OOC) was introduced by G‐C Yang for multimedia optical CDMA systems with multiple quality of service (QoS) requirement. In this article, new infinite classes of optimal (__u, W__, 1, {1/2, 1/2})‐OOCs are obtained for __W__={3, 4}, {3, 5} and {3,

## Abstract Several direct constructions via skew starters and Weil's theorem on character sum estimates are given in this paper for optimal (__gv__, 5, 1) optical orthogonal codes (OOCs) where 60 ≀ __g__ ≀ 180 satisfying __g__ ≑ 0 (mod 20) and __v__ is a product of primes greater than 5. These imp
