Embodiment Construction

[0043] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0044] Since the transmission fiber link medium is easily affected by environmental changes, the link length and refractive index will change, which will affect the transmission delay or phase of the received signal, introduce additional link noise, and reduce the signal-to-noise ratio of the transmitted signal. , causing signal transmission distortion.

[0045] In the prior art, the link is...

Abstract

The invention provides a signal transmission method and device, electronic equipment and a storage medium, and the method comprises the steps that a receiving end receives a first transmission signal from a transmitting end, and the first transmission signal is transmitted to the receiving end through a same link after a second transmission signal and a third transmission signal are modulated to the same optical carrier by the transmitting end; acquiring a second transmission signal and a third transmission signal based on the first transmission signal; acquiring a sampling clock signal based on the second transmission signal; the third transmission signal is sampled based on the sampling clock signal. According to the invention, the second transmission signal and the third transmission signal are transmitted in the same link, so that the sampling clock signal and the third transmission signal undergo the same delay jitter; therefore, phase jitter or time jitter noise generated by link disturbance in the transmission process of the third transmission signal can be directly eliminated, a complex link compensation system in the prior art is avoided, and the stability of signal transmission is enhanced.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a signal transmission method, device, electronic equipment and storage medium. Background technique [0002] With the development of communication technology in our country and the popularization of mobile phones, TVs, computers and other terminals, people's communication, entertainment, work and other activities are increasingly inseparable from various terminals. At this time, the importance of signal transmission between terminals is also increasing. Just getting higher and higher. [0003] For analog signals that need to be transmitted with high stability through optical fibers, such as backhaul sampling of signals received by distributed radar antennas, transmission and collection of signals received by distributed antennas for deep space exploration, it is necessary to remove the delay / delay introduced by the transmission link phase noise to preserve the ...
