Embodiment Construction

[0019] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. A preferred embodiment of the invention is shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0020] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical", "horizontal", "left", "right" and similar expressions are used herein for the purpose of description only.

Abstract

The invention relates to a terahertz digital communication system and method based on polarization coding. The system controls two pulsed terahertz sources respectively according to the digital signal to be transmitted, and the two pulsed terahertz sources respectively generate pulse signals at the moment when the signal is 0 and 1, and then pass the two signals respectively through the polarization unit to form a linearly polarized signal And the polarization directions are orthogonal, the polarized signals of the two lines are synthesized into one signal through the polarization beam splitter and then transmitted. and signal 1 to complete the data transfer. The invention has the advantages of not occupying bandwidth resources, direct and fast modulation, and simple implementation, and is a brand new supplement to the existing terahertz communication scheme. The communication rate is determined by the rate of the pulsed terahertz source. The pulse instantaneous energy of the pulsed terahertz source is high, the power can be made relatively large, and the anti-attenuation ability is stronger than that of the continuous wave.

Description

technical field [0001] The invention relates to the communication field, in particular to a polar coding-based terahertz digital communication system, and also to a polar coding-based terahertz digital communication method. Background technique [0002] The increasing demand for unallocated idle spectrum resources will inevitably make the working frequency of the wireless communication system develop to a higher frequency terahertz (THz) frequency band. The instantaneous transmission of big data will use a higher carrier frequency to meet the needs of high transmission rates. A large number of studies have shown that the application of terahertz communication technology in the field of communication has many advantages compared with today's relatively mature microwave communication and optical fiber communication, such as high transmission rate, good directionality, high security, small scattering, and Good penetration and so on. [0003] At present, the coding schemes of ...
