Description

technical field

[0001] The invention relates to the technical field of communication, in particular to a radiation position modulation communication system and a communication method. Background technique

[0002] Gamma-ray communication is a communication method in which gamma-ray photons are used as carrier signals to transmit information. Gamma rays have strong penetrating power and high energy. They are electromagnetic waves with a wavelength shorter than 0.01 angstroms and a frequency higher than 1.5 trillion hertz. Due to their extremely high penetrating power, using gamma rays for communication is very important for communication in electromagnetic shielding environments is of great significance.

[0003] The gamma-ray carrier frequency is very high and has particle characteristics, which are reflected on the gamma-ray detector 1, and the gamma-ray photons are characterized as discrete pulse trains in time, which has the time resolution capability of the existing gam...
