System and method for improving radio frequency in broadband wireless communication

Abstract

The invention discloses a system and a method for improving radio frequency through broadband wireless communication, and belongs to the technical field of wireless communication, and the system comprises a photoelectric modulator, a photoelectric converter, and a laser. According to the invention, the requirements of radio frequency on a high-speed ADC and a microwave circuit are greatly reduced,and a traditional PLL reference clock configurator is used as a clock source for simulating up-conversion. The clock frequency is influenced by devices, circuits and the like, the design is complex when the frequency is about 100GHz, the cost is relatively high, according to the invention, a broadband photoelectric modulation principle is utilized, under the condition that data transmission is not affected, signals are modulated through laser and then converted into electric signals through a photoelectric converter, due to the fact that the adjustable range of the wavelength of light waves is large, the radio frequency can be greatly improved, a PLL reference clock configurator and a high-speed DAC are omitted, and finally the purposes of improving performance and reducing device complexity are achieved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a system for increasing radio frequency in broadband wireless communication. Background technique [0002] Electricity and light are the most widely used transmission media in the field of information. Electricity, as a traditional and universal transmission medium, plays a pivotal role in various information systems, but it has some inevitable defects. Light, as a new transmission medium, has many advantages over electricity. Light is currently gradually replacing electricity in some specific areas, such as communication systems. However, in view of the fact that most of the current information systems are still based on electrical signals, and electrical signals are affected by devices in the radio frequency field, it is difficult to achieve a frequency of hundreds of GHz. Therefore, electricity can be used to modulate light and load signals on light. The elec...

Problems solved by technology

The disadvantage of this method is that when the RF frequency is high, the analog mixers are cascaded more, the structure is complex, and the design is difficult

And affected by the device, the mixer clock is difficult to achieve more than 100 GHz, so it is difficult to design a radio frequency solution of more than 100 GHz in traditional electronics solutions, and existing devices cannot meet the requirements
