Abstract
Accelerating global informatization, satellite communication plays a key role in many fields due to its long-distance and wide coverage characteristics. However, its link length, signal attenuation and vulnerability to interference bring challenges to communication quality and reliability. Especially in the complex electromagnetic environment, the traditional system is difficult to resist the interference, which increases the risk of communication interruption and information leakage. Therefore, the research and application of anti-interference technology are crucial to ensure the communication security. This paper focuses on the anti-interference technology in satellite communication, summarizing the basic knowledge and the classification of anti-interference technologies. This paper analyzes the main problems facing the current technology application, such as signal processing complexity, modulation and demodulation technology limitations, encryption technology challenges and hardware resource limitations. In view of these problems, optimization strategies, including signal processing optimization, technical innovation, encryption technology upgrade and hardware resource management, are proposed to improve the anti-interference ability and performance of the system. Finally, summarize the research results and look into the future development direction.
