The invention relates to a signal receiving method and device and a signal transmission system, and relates to the field of wireless communication. The method comprises the following steps: acquiring channel characteristics of a feed link channel adopted when each satellite forwards a signal; according to the channel characteristics of the reference feed link channel, calculating the compensation parameters of the channel characteristics of other feed link channels, wherein the reference feed link channel is a feed link channel adopted by a reference satellite in the satellites, the other channel characteristics are feed link channels adopted by other satellites in the satellites, and the compensation parameters enable the channel characteristics of other feed link channels to be consistent with the channel characteristics of the reference feed link channel; and under the condition that the terminal forwards the user signal through each satellite, fusing the forwarding signal of the reference satellite and each compensation signal into a receiving signal of the user signal, wherein each compensation signal is a forwarding signal of other satellites processed according to each channel compensation parameter.
Description
technical field [0001] The present disclosure relates to the field of wireless communication, and in particular to a signal receiving method, a signal receiving device, a signal transmission system and a non-volatile computer-readable storage medium. Background technique [0002] At present, the field of satellite communication mainly includes two types: synchronous orbit communication and non-synchronous orbit communication system. According to the International Radio Regulations, low-orbit communication systems must avoid geosynchronous orbit communication systems. [0003] In the related art, the low-orbit communication system adopts lower transmission power to avoid interference to signals of the high-orbit communication system. Contents of the invention [0004] The inventors of the present disclosure have discovered the following problems in the above-mentioned related technologies: the requirement for a large communication bandwidth cannot be met, and the network p...
