    Sparse code multiplexing access (SCMA) is a new code-domain non-orthogonal technique in the fifth generation mobile communication (5G), which can improve the quality of single-user link by orthogonal chirp-chirp division multiplexing (OCDM) modulation. In this paper, a SCMA-OCDM multi-core fiber tra...

    3D PCDM Probabilistic Shaping Transmission Scheme Based on Chaotic Constellation Mapping

    3D PCDM Probabilistic Shaping Transmission Scheme Based on Chaotic Constellation Mapping द्वारा Mengjie Wu, Bo Liu, Jianxin Ren, Yu Bai, Zeqian Guo, Shuyu Zhou, Yilan Ma, Gengyin Chen, Yongyi Yu, Xiangyu Wu, Yaya Mao, Feng Wang, Yongfeng Wu, Lilong Zhao

    प्रकाशित 2023-01-01

    In this article, a high-security three-dimensional (3D) probabilistic shaping optical transmission system based on prefix-free code distribution matching (PCDM) and Polar code joint coding is proposed. The bit error rate (BER) performance of the communication system is optimized by using the probabi...
