Problems solved by technology
[0004] However, in the process of X-ray communication, the signal strength received by the receiving end will decrease rapidly with the increase of the communication distance, which will affect the signal transmission to a certain extent, causing the information to be distorted or lost
At the same time, the X-ray communication system, like other communication systems, has a lot of background X-ray noise in the channel, which may cover up the signal and reduce the signal quality

The invention provides a signal receiving method for reducing an X-ray communication error rate and a receiving device thereof. The signal receiving method comprises the following steps: amplifying a received X-ray signal to obtain an amplified X-ray signal; performing pulse identification extraction on the amplified X-ray signal to obtain two paths of pulse signals; sampling the two paths of pulse signals to obtain two paths of sampling signals; performing noise filtering on the two paths of sampling signals to obtain a path of digital signal; performing time slot synchronous clock signal recovery on the digital signal; performing data judgment to obtain a binary code element signal; and transmitting the binary code element signal to a lower computer for demodulation and decoding.
Description
technical field [0001] The present application relates to the field of communication technology, in particular to a signal receiving method and a receiving device thereof for reducing the bit error rate of X-ray communication. Background technique [0002] X-ray communication is a communication method that uses X-rays as the carrier for information transmission. It was first proposed by Dr. Keith Gendreau of NASA Goddard Space Flight Center in 2007, and it was used in a 600-meter vacuum transmission pipeline of NASA. Its feasibility is preliminarily verified. [0003] The X-ray communication system is based on the principle of intensity modulation / direct detection, that is, the binary digital signal is loaded on the X-ray pulse sequence for transmission, and the receiving end uses the X-ray detector to receive the signal and obtain it by judging whether there is an X-ray pulse in a unit time slot. Information loaded on the ray pulse sequence. [0004] However, in the proce...
