Problems solved by technology

[0004] The current X-ray tube has poor monochromaticity, and can only use the degree of freedom of X-ray intensity to transmit information. The existing X-ray communication systems are all based on the principle of intensity modulation / direct detection
Due to the nonlinear characteristics of the X-ray source modulation curve, the current X-ray communication system can only achieve low-order pulse amplitude modulation, and its communication rate is low

Abstract

The invention relates to the field of space communication, in particular to an X-ray communication method based on space superposition pulse amplitude modulation, which is used for a transmitting end and comprises the following steps: modulating and generating a plurality of low-order pulse electric signals based on to-be-transmitted data; synchronously generating a plurality of X-ray low-order pulses based on the low-order pulse electric signals; performing spatial superposition on the plurality of X-ray low-order pulses to obtain an X-ray high-order pulse; and sending the X-ray high-order pulse to a receiving end.

Description

technical field [0001] The present application relates to the field of space communication, in particular to an X-ray communication method, communication equipment and electronic equipment based on space superposition pulse amplitude modulation. Background technique [0002] X-ray communication is a communication method that uses X-rays as the carrier for information transmission. Since X-rays transmit in a vacuum environment without physical attenuation, the frequency is several orders of magnitude higher than radio frequency, and has the advantages of low divergence and high bandwidth. It is considered to be the next generation of space communication technology. Since X-rays can penetrate plasma without attenuation and have almost no physical attenuation in vacuum transmission, X-rays can be used to realize "black barrier" communication and deep space communication. [0003] In the X-ray communication system, a series of key components such as the X-ray source and the pow...
