摘要
为了满足多媒体光码分多址多种不同的服务质量要求,杨谷章引入了变重量光正交码.本文首次引入参数为(W,Q)的半循环可分组设计来构造变重量光正交码.因此,通过参数为(W,Q)的半循环可分组设计和完备相对差族可构造几类新的最优平衡(v,{3,4},1)变重量光正交码.
Variable-weight optical orthogonal codes(OOCs)were introduced by Yang for multimedia optical CDMA systems with multiple quality of service(QoS)requirements.In this paper,(W,Q)semi-cyclic group divisible designs((W,Q)-SCGDDs)are first introduced to construct variable-weight OOCs.Consequently,several new optimal balanced(v,{3,4},1)-OOCs are obtained by using(W,Q)-SCGDDs and perfect relative difference families.
