摘要 变重量光正交码用于光码分多址通信系统以满足不同服务质量用户需求.给出当u≥5为素数时,最优(16u,{3,5},1,{2/3,1/3))交重量光正交码的具体构造.同时证明了当u≥5为素数时,存在一个最优(25u,{3,4,5},1,{1/4,2/4,1/4})变重量光正交码.这将改进变重量光正交码的存在性结果. Variable-weight optical orthogonM codes (OOCs) can be used in CDMA systems to meet the demand on multiple quality of services. In this paper, it is proved that there exists an optimal (16u, {3,5}, 1, {2/3, 1/3})-OOC for every prime u 〉 5, and an optimal (25u, {3, 4, 5}, 1, {1/4, 2/4, 1/4})-OOC for every prime u k 5.
