X-ray communication scheme with gated X-ray source as emitter and single-photon detector based on microchannel plate as receiver is proposed.The space-speech communication system based on X-ray is set up, and the signal modulation transmitter, Based on the design and working principle of X-ray single-photon detector and signal receiver demodulator of microchannel plate, the preliminary experimental results of space-speech communication system based on X-ray are reported, and the speech signal modulation based on speech signal is better than 20 kbit / s Of X-ray communication.Experimental analysis of the communication performance under different X-ray intensity, signal shaping time and threshold settings, concluded that the X-ray emission power limits the X-ray communication rate conclusion, put forward the next step to improve X-ray communication performance improve proposals.
