Multi-level modulation scheme based on PAK algorithm for optical camera communications
文献摘要：
In an optical camera communication(OCC)system,multi-level modulation is essential for data rate enhancement with the finite frame rate of the receiving camera constraint,where the K-means algorithm is widely used as a thresholding scheme.The result of K-means clustering is sensitive to initial cluster centers.In this paper,we propose a multi-level modulation scheme utilizing the pilot-aided K-means(PAK)algorithm.PAK algorithm innovates in both obtaining the state of the stripes propagated through the optical channel under different environments and overcoming the suscepti-bility of K-means.Our scheme could prompt data rate and improve the performance of OCC.Finally,non-orthogonal multiple access(NOMA)pattern is designed based on the proposed scheme to achieve multiplex communications.
