6 G integrated satellite and terrestrial converged network is an evolution of next-generation communication technology, which is dedicated to deeply integrating satellite communications with terrestrial networks to achieve more powerful communication performance. However, multipath interference may pose a challenge to its transmission quality and reliability, and effective suppression techniques are needed to improve the robustness of the system. To address this challenge, this paper proposes an Orthogonal Time Frequency Space (OTFS) - based adaptive dynamic threshold detection and interference suppression method as a means of resisting the common multipath jamming in star-ground transmission systems. Experimental results show that the method significantly improves the robustness and reliability of the space-ground transmission system.

摘要

6 G integrated satellite and terrestrial converged network is an evolution of next-generation communication technology, which is dedicated to deeply integrating satellite communications with terrestrial networks to achieve more powerful communication performance. However, multipath interference may pose a challenge to its transmission quality and reliability, and effective suppression techniques are needed to improve the robustness of the system. To address this challenge, this paper proposes an Orthogonal Time Frequency Space (OTFS) - based adaptive dynamic threshold detection and interference suppression method as a means of resisting the common multipath jamming in star-ground transmission systems. Experimental results show that the method significantly improves the robustness and reliability of the space-ground transmission system.
