Abstract

The invention relates to a terahertz wave modulation method and a wireless communication system. Among them, the modulation method of the terahertz wave includes: generating a digital signal composed of 0 and 1 according to the data to be transmitted; determining the transmission period of the digital signal; transmitting a pulsed radio signal at each moment when the digital signal is 1, and transmitting a pulsed radio signal when the digital signal is 0. The empty signal is transmitted at each time; wherein, the pulse width of the pulsed radio signal is 1fs‑1000fs. The modulation method of the terahertz wave mentioned above, by transmitting the femtosecond-level terahertz short wave in the terahertz channel, can effectively reduce the probability of mutual interference between signals while realizing ultra-high-speed communication. In addition, pulsed radio signals and empty signals The method of alternate transmission also improves the accuracy of signal transmission, and effectively overcomes the characteristics of path attenuation and delay expansion of terahertz channels.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a terahertz wave modulation method and a terahertz wave wireless communication system. Background technique [0002] With the rapid development of communication technology, the 300MHz to 30GHz microwave frequency band used by existing wireless mobile communications is already very crowded, which limits the maximum achievable wireless transmission rate of data. The latest 5G standard has officially adopted the new 30GHz to 300GHz millimeter wave spectrum, and the 100GHz to 10THz terahertz frequency band adjacent to the millimeter wave frequency band has also received close attention from academia and industry in recent years. 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 hig...
