Embodiment Construction

[0031] The scene used in the present invention is as figure 1 shown. When the aircraft flies in the atmosphere, the plasma sheath will cover the surface and surrounding area of ​​the aircraft, blocking the signal transmission of traditional microwave wireless communication systems. Therefore, the present invention is adopted to avoid the situation that the signal transmission is blocked.

[0032] The present invention is a terahertz wireless transmitter used for high-speed communication in the black barrier area. The working frequency band of the transmitter is higher than 300 GHz. Figure 1-3 Among them, it can be designed as 0.3~10 THz.

[0033] The transmitter includes a framing module, an error correction coding module, an interleaving module, a symbol mapping module, a shaping filter module, a DAC, an I / Q mixer, a bandpass filter, a power amplifier, and a power amplifier in sequence according to the sending direction of information. The output end is connected to a fee...

Abstract

The invention discloses a terahertz wireless transmitter applied to high-speed wireless communication of a blackout area. The transmitter sequentially comprises a framing module, an error correction and coding module, an interweaving module, a symbol mapping module, a molding and filtering module, a digital-to-analog converter, an I / Q frequency mixer, a band pass filter (BPF) and a power amplifier(PA); the output end of the PA is connected with a feed source network, and the feed source network is provided with an amplitude-phase adjustment component under the control of an amplitude-phase adjustment and control module; in the feed source network, under the control of the amplitude-phase adjustment and control module, after being subjected to amplitude and phase adjustment of the amplitude-phase adjustment component, a terahertz radio frequency signal is transmitted out according to a certain beam direction. According to the transmitter provided by the invention, the working terahertzfrequency band is higher than 300 GHz, penetration through a plasma sheath set can be achieved, a directional beam with adjustable beam orientation can be generated, and transmission of the wirelesstransmission signal can be achieved.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a terahertz wireless transmitter used for high-speed communication in blackout areas. Background technique [0002] When the high-speed aircraft flies in the adjacent space, due to the intense friction and extrusion with the atmosphere, the surface temperature rises sharply to above 3,000 Kelvin, which causes the ionization of atmospheric molecules, so that the electrons orbiting the nucleus in the atmospheric molecules break away from the shackles of the nucleus and form a free space. electrons, atmospheric molecules that have lost electrons form positively charged ions. Free electrons and ions form a plasma on the surface of the vehicle. In addition, due to the ionization of the heat insulation material of the aircraft itself under high temperature ablation, the surrounding electron concentration increases significantly, forming a plasma with a certain thickness surrounding...
