Autor: Jiexin Chen, Qi Zhang, Qihan Zhao, Xiangjun Xin, Ran Gao, Haipeng Yao, Feng Tian, Yongjun Wang, Qinghua Tian, Leijing Yang, Lan Rao, Fu Wang, Sitong Zhou

Publikováno v: Photonics, Vol 11, Iss 7, p 584 (2024)

In this paper, a subset-optimized eight-dimensional trellis-coded quadrature amplitude modulation (SO-8DTCM-16QAM) format for higher-order constellations in high-speed optical communications is proposed. This scheme increases the number of subsets of

Modulation Format Identification Based on Signal Constellation Diagrams and Support Vector Machine

Autor: Zhiqi Huang, Qi Zhang, Xiangjun Xin, Haipeng Yao, Ran Gao, Jinkun Jiang, Feng Tian, Bingchun Liu, Fu Wang, Qinghua Tian, Yongjun Wang, Leijing Yang

Publikováno v: Photonics, Vol 9, Iss 12, p 927 (2022)

In coherent optical communication systems, where multiple modulation formats are mixed and variable, the correct identification of signal modulation formats provides the foundation for subsequent performance improvement using digital algorithms. A mo
