Embodiment Construction

[0018] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0019] The invention is a multi-channel parallel processing space-based frequency-hopping data link system, which includes a radio frequency module and a baseband module, and can realize frequency-hopping and time-hopping communication with multiple channels, broadband, and multiple frequency points.

[0020] figure 1 A space-based frequency-hopping data link system with multi-channel parallel processing is described.

[0021] When receiving signals, the RF module can amplify and down-convert the RF signals received by the antenna into multiple intermediate frequency signals. The baseband module receives multiple intermediate frequency signals at the same time, converts the intermediate frequency analog signals into baseband digital signals, and quantifies the baseband digital signals Digital demodulation, channel decoding, etc.

Abstract

The invention discloses a space-based frequency-hopping data link hardware architecture for multi-channel parallel processing, including a radio frequency module and a baseband module. The radio frequency module can amplify the radio frequency signal received by the satellite on-board antenna and down-convert it into multiple intermediate frequency signals; Demodulation, channel decoding, etc.; encode and modulate the baseband digital signal after processing, and output an intermediate frequency signal to the radio frequency module; the radio frequency module amplifies the intermediate frequency signal after up-conversion, and then transmits it through the on-board antenna. The invention supports the frequency-hopping and time-hopping communication system of broadband multi-frequency points. It has the advantages of high reliability, high anti-interference, high confidentiality, high user rate, simple hardware structure, and low cost.

Description

technical field [0001] The invention relates to the field of aerospace communication, in particular to a multi-channel parallel processing space-based frequency-hopping data link system. Background technique [0002] The space-based data link is a system that uses satellite communication channels and satellite communication protocols to transmit various information to realize the data connection between satellites and users. Space-based data links are widely used in various fields due to their characteristics of over-the-horizon, high bandwidth, strong environmental adaptability, strong anti-interference ability, and stable and reliable transmission channels. [0003] The current space-based data link hardware architecture is FPGA+AD+DA. The information to be transmitted uses a fixed bandwidth, and the signal is modulated to a fixed frequency band, and then transmitted in the channel. This communication method has fewer communication frequencies. Poor anti-interference perf...
