It is especially suitable for miniaturized, low-power, and low-cost spaceborne equipment, and the multi-rate working mode can meet various types of data communication.

Description

technical field [0001] In particular, the present invention relates to a multi-rate Ku communication transmitting device with variable frequency points based on block coding. Background technique [0002] The transmission signal quality of low-orbit communication satellites is not only related to the natural environment such as weather and rain attenuation, but also to the orbit of operation. At the same time, the satellite energy is limited to a certain extent. Traditional satellites have a fixed working rate and fixed output power, and cannot change the working mode according to the actual environment to achieve the best efficiency. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to avoid the deficiencies in the above-mentioned background technologies, and proposes a multi-rate Ku communication transmitting device with variable frequency points based on block coding, which can solve the above deficiencies. It is especiall...

AI Technical Summary

Problems solved by technology

[0002] When low-orbit communication satellites work, the transmission signal quality is not only related to the natural environment such as weather and rain attenuation, but also related to the orbit of operation. At the same time, the energy of the satellite is limited, and it cannot guarantee that the equipment will be turned on at all times or output signals at the maximum power.

The working speed and output power of traditional satellites are fixed, and the working mode cannot be changed according to the actual environment to achieve the best efficiency
