Doppler Delay-Time Frequency Cross-Domain Joint High Security Transmission Scheme Based on Orthogonal Time Frequency Space
Published 2023-01-01Get full textA doppler delay-time frequency (DD-TF) cross-domain high-security transmission scheme based on orthogonal time frequency space (OTFS) is proposed, which is compatible with high-speed and large-capacity optical transmission systems. In this scheme, 36 sets of chaotic sequences are mapped out through...

High-Security Multi-Level Joint Encryption Scheme Based on SCMA Chaotic Codebook and OCDM Subcarrier Disturbance
Published 2023-01-01Get full textSparse 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
Published 2023-01-01Get full textIn 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...
