Abstract

The invention relates to a microwave photon millimeter wave ultra-wideband signal generation method and device based on up-conversion, belonging to the technical field of microwave photonics. A lasersource, a polarization controller, an arbitrary waveform generator, a microwave signal source, a dual-parallel Mach-Zehnder modulator, an erbium-doped fib amplifier, an optical isolator, a first annulator, a single-mode optical fiber, a second annulator, a photodetector and a spectrum analyzer constitute the device. The invention is based on the up-conversion technology to generate the signal at 22GHz-29GHz millimeter wave UWB signal, the upconversion realized by SSB modulation can overcome the dispersion effect in single-mode fiber, so that the UWB signal can be transmitted over long distance. Single sideband modulation using secondary Brillouin scattering is simple and easy to implement. Moreover, the amplification of Brillouin gain and the attenuation of loss make the spectrum of the generated UWB signal satisfy the power spectral density mask specified by the Federal Communications Commission of the United States.

Description

Technical field [0001] The invention belongs to the technical field of microwave photonics, and specifically relates to a method and device for generating microwave photonic millimeter wave ultra-wideband signals based on up-conversion. Background technique [0002] With the rapid development of wireless communication technology, various types of wireless communication systems have been developed one after another, and the available frequency spectrum is becoming increasingly saturated. However, people's requirements for wireless communication systems are still increasing, in order to achieve faster data transmission rates, lower costs, and lower power consumption. In the context of such a demand, ultra-wideband signals have attracted widespread attention and have become a hot issue in the research and development of wireless communications. Ultra-wideband signals can be used in short-range large-capacity wireless communications and sensor networks due to their low power consump...
