YANG for multimedia optical CDMA systems with multiple quality of service （QoS） requirements. In this paper, some infinite classes of optimal cyclic packing are presented. Optimal （24u, {3, 4}, 1, {2/3, 1/3}）-OOCs for any positive integer u 〉 1 are established.展开更多
Variable-weight optical orthogonal code(VWOOC)has many important applications in communica tions.In this paper,we obtain several series of optimal(v,W,1,Q)OOCs for W--{3,6},{3,4,6}.

Yang [IEEE Trans. Commun., 1996, 44： 47-55] for multimedia optical CDMA systems with multiple quality of service （QoS） requirements. In this paper, seven new infinite classes of optimal （v, {3,4,6}, 1, Q）-OOCs are constructed.展开更多

文摘Variable-weight optical orthogonal codes （OOCs） were introduced by G. C. YANG for multimedia optical CDMA systems with multiple quality of service （QoS） requirements. In this paper, some infinite classes of optimal cyclic packing are presented. Optimal （24u, {3, 4}, 1, {2/3, 1/3}）-OOCs for any positive integer u 〉 1 are established.
