Multi-rate Ku communication transmitting device with variable frequency points based on block coding

Abstract

The invention discloses a frequency point variable multi-rate Ku communication transmitting device based on block coding. The device includes: an analog signal acquisition module, a CAN remote control and telemetering module, a service data receiving and splitting module, a scrambling module, a coding module, a unique word adding and framing module, a shaping filtering and interpolation filtering module, an output frequency point control and digital modulation module and an up-conversion module. The CAN remote control telemetering module completes a remote control function, controls the working mode and the working rate of the service data receiving and splitting module, controls the shaping filtering and interpolation filtering module to complete data shaping filtering of different carrier wave rates, and controls the output frequency point control and digital modulation module to carry out frequency point conversion. The device can quickly determine the current working state of the equipment, and is simple in transmission frame structure, flexible in data processing, low in hardware requirement, good in portability and the like. The device is especially suitable for miniaturized, low-power-consumption and low-cost satellite-borne equipment, and the multi-rate working mode can meet the communication use of various different types of data.

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
