To exploit the attractive features of CDMA systems and the tremendous bandwidth provided by optical communication such as fiber, VLC, and Li-FI channel, a new system is emerging and is known as optical code division multiple access. These systems require optical orthogonal codes (OOCs). This paper presents an algorithm to design OOCs and determines the auto-correlation (\(\lambda _a\)) and cross-correlation (\(\lambda _c\)) constrains of codes. The grouping of these OOCs for desired \(\lambda _a\) and \(\lambda _c\) is done using a low complexity bipartite method. Design of codes, groups, and simulation for performance analysis in terms of multiple access interference is done using MATLAB programming. The bipartite scheme for grouping finds all possible groups and it reduced the time of computation. The memory requirement of the scheme is also reduced together with computational complexity.

为了利用CDMA系统的吸引人的特征以及诸如光纤，VLC和Li-FI信道之类的光通信所提供的巨大带宽，一种新的系统正在出现，并且被称为光码分多址。这些系统需要光学正交码（OOC）。本文提出了一种设计OOC的算法，并确定了代码的自相关（\（\ lambda _a \））和互相关（\（\ lambda _c \））约束。所需\（\ lambda _a \）和\（\ lambda _c \）的这些OOC的分组使用低复杂度的二分法完成。使用MATLAB编程完成了针对多址干扰的性能分析代码，组和仿真的设计。用于分组的二分方案可找到所有可能的组，从而减少了计算时间。该方案的存储需求也与计算复杂度一起降低。
