We describe the details of an optical communication system using Gaussian vortex beams (GVBs). Our main focus will be on the detection strategy. The transmitter encodes the message symbols into the topological charges of the GVBs. Then the receiver implements a detection strategy based on the orthogonality of the GVBs. The graphical results obtained from the related theoretical derivation indicate that this detection strategy has almost no bounds. Thus, it is concluded that the performance of such a system can only be practically limited.

使用高斯涡旋光束的光通信系统

我们描述了使用高斯涡旋光束（GVB）的光通信系统的细节。我们的主要重点将放在检测策略上。发射机将消息符号编码为GVB的拓扑电荷。然后，接收器基于GVB的正交性实施检测策略。从相关的理论推导获得的图形结果表明，这种检测策略几乎没有界限。因此，可以得出结论，这种系统的性能实际上只能受到限制。
