变权光正交码(OOC)是由G-C Yang为具有多种服务质量(Qos)要求的多媒体光码分多址系统而提出的。本文给出了一种基于循环差分族的最优变权OOC的构造方法。给出了循环差分族的几个新的构造。利用这些构造，构造了2°|W|°4的新的最优(n，W，1，q)-OOC。
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 paper, a construction for optimal variable-weight OOCs via cyclic difference families is given. Several new constructions for cyclic difference families are also given. By using these constructions, new optimal (n, W, 1, Q)-OOCs for 2 ¿ |W| ¿ 4 are constructed.
