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.

[0021] Unless other...

Abstract

The invention relates to a terahertz digital communication system and method based on polarization coding. The method comprises the steps that the system controls two pulse terahertz sources according to a to-be-transmitted digital signal, and the two pulse terahertz sources respectively generate pulse signals at moments when the signals are 0 and 1; the two signals are enabled to pass through polarization units to form linear polarization signals, wherein the polarization directions are perpendicular to each other; the two linear polarization signals are combined to form a signal through a polarization beam splitter, and then the signal is transmitted; a receiving end receives the signal, and then reverts the signal to two signals; and then two signals are demodulated by a terahertz detector into signals 0 and 1, thereby completing the data transmission. The system and method do not occupy the bandwidth resource, carry out the direct and rapid modulation, is simple in implementation, and is a brand-new supplement for a conventional terahertz communication scheme. The communication rate is determined by the rates of the pulse terahertz sources. The pulse instantaneous energy of the pulse terahertz sources is high, so the power can be bigger, and the anti-damping capacity is stronger than that of a 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 ...
