Abstract

The embodiment of the present invention relates to a wireless signal transceiver device, which includes: an antenna, a low-noise amplifier, a mixer, a frequency generator, a limiting amplifier, a modulator and a photoelectric converter; the antenna is used to receive pulse signals; the low-noise amplifier is used to It performs low-noise amplification processing on the pulse signal received by the antenna to generate a processed pulse signal and sends it to the mixer; the frequency generator is used to generate a frequency signal and sends it to the mixer; the mixer processes the frequency signal into Communication electrical signals; the limiting amplifier is used to limit and amplify the communication electrical signals to generate an amplified electrical signal; the modulator is used to convert the amplified electrical signal into a protocol to generate an electrical signal; the photoelectric converter is used to convert the electrical signal into an optical signal. sent to the optical receiver. The invention combines millimeter wave communication technology and optical communication technology, and uses a dedicated communication protocol to realize large-capacity and highly reliable data communication between the train and the ground under high-speed moving conditions.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a wireless signal transceiving device and a wireless signal transceiving chain. Background technique

[0002] So far, the purpose of all mobile communication systems is to solve personal communication. Therefore, from the first generation mobile communication system to the current 5G mobile communication system, all the development of mobile communication technology is to improve the quality of personal communication. Therefore, it is unrealistic to try to solve the vehicle-to-ground communication of high-speed trains under wide-area conditions based on the existing mobile communication technology or existing infrastructure. In fact, GSM-R, which evolved from GSM technology, is increasingly unable to meet the increasingly urgent information and intelligent vehicle-to-ground communication needs of high-speed railway transportation, and there is no effective progress in this...
