Abstract

The invention relates to a high-capacity orbital angular momentum hybrid multiplexing communication method and a test method thereof. The test method comprises the following steps: performing orbitalangular momentum multiplexing, polarization division multiplexing and frequency division multiplexing on multiple paths of vortex optical signals generated by Gaussian beams in sequence to synthesizeone path of optical signals; emitting the multiplexed optical signal to atmospheric turbulence, wherein the atmospheric turbulence is simulated by a multi-layer phase screen; and measuring the parameters of the communication. Compared with the conventional technology, the communication method provided by the invention can improve the communication capacity and rate.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a high-capacity orbital angular momentum hybrid multiplexing communication method and a testing method thereof. Background technique [0002] With the increasing popularity of the Internet and the rapid development of the communication industry, people have higher and higher requirements for communication speed and capacity. High-speed and high-capacity communication is an inevitable trend of future communication development. [0003] At present, the multiplexing technology in communication includes wavelength division multiplexing, time division multiplexing and other technologies, but the communication rate and capacity of these multiplexing technologies are still far from meeting the development needs of the emerging communication field. Providing new communication multiplexing methods has also become an urgent need for the development of the communication industry. C...
