A Spectrum Adaptive High Performance Communication System and Method

Abstract

The present invention is a spectrum self-adaptive high-performance communication system and method, which is suitable for multifunctional dynamic reconstruction of communication equipment and spectrum self-adaptive high-performance communication in ground, aviation, aerospace and other occasions, mainly including a receiving antenna module, a down-conversion Module, digital channelization and processing evaluation module, transmitting antenna module, adaptive up-conversion module and other five parts, combining and parallel application of broadband spectrum monitoring function, signal analysis and processing function, communication function and other functions, using high-performance signal receiving ability , realize real-time spectrum monitoring in the large-bandwidth working frequency band, and evaluate the current communication link in real time. When the link or signal is found to be interfered, it will adaptively select and adjust the communication parameters to realize spectrum adaptive high-performance communication. The invention realizes the frequency spectrum self-adaptive communication function when the communication process is disturbed, and at the same time improves the frequency spectrum resource utilization efficiency and communication efficiency of the satellite communication.

Description

technical field [0001] The invention relates to a frequency spectrum self-adaptive high-performance communication system and method, belonging to the technical field of civil communication and the overall technical field of aerospace. Background technique [0002] At present, the communication spectrum resources are limited and the utilization rate is low, and the global communication is facing the urgent need to improve the reliable communication ability under the interference of the electromagnetic environment. During the communication process, the communication system is seriously interfered by other radio equipment, channel blockage and communication interruption occur frequently, which seriously reduces the availability of the communication system, and cannot effectively exert its economic and social benefits. Reliable communication technology in complex electromagnetic environments needs to be broken through. Civil application requirements such as civil disaster reduct...
