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, 6}. Β© 2010 Wiley Periodicals, Inc. J Combin Designs 18: 274–291, 2010

## Abstract By a (__Ξ½__, __k__, 1)‐OOC we mean an optical orthogonal code. In this paper, it is proved that an optimal (4__p__, 5, 1)‐OOC exists for prime __p__ ≑ 1 (mod 10), and that an optimal (4__up__, 5, 1)‐OOC exists for __u__ = 2, 3 and prime __p__ ≑ 11 (mod 20). These results are obtained by

The algebraic geometric code is known as a linear code that guarantees a relatively large minimum distance under the condition that the number of check symbols is kept constant, when the code length is long. Recently, Saints and Heegard presented a unified theory for decoding of the algebraic geomet
