The positive impact of data elements on enterprise operation has been confirmed by many scholars, but few studies have paid attention to the effect of data elements on corporate green transformation, especially in the context of global climate change. In this study, we employ panel data from Chinese...

In this paper, a high-security chaos encryption with dynamic probability for 16-carrier-less amplitude/phase (CAP) PON is proposed by using two-layer chaos map with feedforward neural network-based XOR operator (FNNXOR). The inner chaotic map is divided into several time slots, and the ke...

A 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...

In this paper, for the first time, a novel multi-level constellation compression modulation (MCCM) is proposed and applied for generalized frequency division multiplexing passive optical network (GFDM-PON). The principle of the proposed MCCM is to transfer the constellation points of the outer circl...

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...

Magnetic holes (MHs) are structures commonly observed in various space plasma environments throughout the solar system, including the solar wind. These structures are characterized by a localized decrease in magnetic field strength, coincident with an increase in plasma density. Previous observation...

This paper proposes a multi-domain multi-level (MDML) orthogonal frequency division multiplexing (OFDM) optical encryption transmission scheme based on memristor Rulkov neuron chaos. In this scheme, the masking factors generated by the memristor Rulkov neuron chaos are used to encrypt the informatio...

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...
