论文摘要
自早期以来，连贯性一直用作光学通信的资源。它被广泛用于数据的多路复用，但不用于数据编码。在这里，我们介绍了一种编码方案，我们称之为\ textit {相互一致的编码}，以编码空间分离光束的相互连贯性中的信息。我们通过得出相关的相关数字（信噪比，最大比特率和光谱效率）来描述其实现并分析其性能。相互的一致性编码得出的传输信号数量具有二次缩放，该信号的数量具有使用的光束数量，这可能对加密和数据安全性有好处。
Coherence has been used as a resource for optical communications since its earliest days. It is widely used for multiplexing of data, but not for encoding of data. Here we introduce a coding scheme, which we call \textit{mutual coherence coding}, to encode information in the mutual coherence of spatially separated light beams. We describe its implementation and analyze its performance by deriving the relevant figures of merit (signal-to-noise ratio, maximum bit-rate, and spectral efficiency) with respect to the number of transmitted beams. Mutual coherence coding yields a quadratic scaling of the number of transmitted signals with the number of employed light beams, which might have benefits for cryptography and data security.
