Embodiment Construction

[0050] The present invention will be further described below in combination with specific embodiments.

[0051] The schematic diagram of the intelligent optimized four-dimensional chaotic vector encryption orthogonal transmission system proposed by the present invention is as follows: Figure 9 shown. A high-security orthogonal mode division multiplexing transmission system, which can be roughly divided into an orthogonal mode modulation module, a coded modulation module, an orthogonal mode division multiplexing / demultiplexing module, and a demodulation and decoding module. The core innovation of the present invention The point lies in the encryption technology in the coded modulation module.

[0052] The flow of the entire transmission system is as follows: first, a narrow linewidth continuous Gaussian beam with constant power is generated by a narrow linewidth continuous laser, and then the light is split by a beam splitter to obtain multiple Gaussian lights with the same w...

Abstract

The invention discloses an intelligent optimization four-dimensional chaotic vector encryption orthogonal transmission method. The invention belongs to the technical field of information transmission,the method is based on an orthogonal mode division multiplexing transmission system. A communication system is encrypted from four dimensions of communication constellation, OFDM subcarrier frequency, the time and the mode; enough key space can be provided by multi-dimensional hyper-chaotic encryption to provide powerful guarantee for communication security, innovatively utilize machine learningto multi-dimensional encryption optimization, and realize coordination optimization between dimensions, thereby effectively reducing the time of an encryption processing process, and reducing the negative efficiency of the communication system with encryption steps in the digital signal processing module. Compared with a traditional encryption transmission scheme, the scheme provided by the invention has more powerful security guarantee, and the encryption cost is lower.

Description

technical field [0001] The invention belongs to the technical field of information transmission, and in particular relates to an intelligent optimized four-dimensional chaotic vector encryption orthogonal transmission method. Background technique [0002] In recent years, due to the rapid development of information technology and the increase in people's demand for network capacity, data communication bandwidth continues to grow at a rate of 20% to 40% per year, and high-quality, high-speed information transmission has become one of the most urgent needs of people. . And the world is about to usher in the 5G era. China's Huawei, as one of the leaders of 5G standards, has made China at the forefront of 5G. Therefore, China's communication field will be oriented to a wider space, more new space needs to be expanded, and more new services will be developed. All of these make communication technology have higher and higher requirements on indicators such as spectrum rate, user...
