—Variable-weight optical orthogonal code (OOC) was introduced by Yang for multimedia optical CDMA systems with multiple quality of service (QoS) requirements. In this paper, the upper bound on the size of variable-weight OOCs is improved , a cyclic t-(v; W; ; Q) packing is introduced to construct a variable-weight OOC, an upper bound for the number of(More)
