摘要
光正交码是用于光CDMA系统中的一种优选地址码,它是一个二元(0,1)序列族,具有良好的相关特性。文章在复合长度光正交码(Multi-length-OOC)的理论研究基础上,提出了一种基于Multilength-OOC理论的不完全优化光正交码构造算法;借助计算机仿真设计,得到了一组光正交码;仿真结果表明,基于Multi-length-OOC的构造算法的可行性与准确性。
The optical orthogonal code(OOC),which is a kind of preferred address code generally used in optical CDMA systems, is a family of binary (0, 1)-sequences with good auto-and cross-correlation properties. The theory of the multi-length optical orthogonal code(multi-length OOC) is introduced. A construction algorithm for the incomplete optimized OOC based on the multi-length OOC theory is presented. A set of OOCs are gained by means of computer simulation. The simulation results show that the construction algorithm based on the multi-length OOC is feasible.
