Guomin Tang, Lidong Zhu, Qi Hang Wu, Qihui He, Le Yu · 2021
The openness of satellite communication channel makes satellite signal easy to be intercepted and decoded by non-partners, so it’s necessary to adopt secure communication technologies in satellite communication systems. Based on the existing hybrid spread-frequency technology, this paper introduces chaotic sequence to control system frequency hopping and code-hopping, puts forward a new type of safe communication method combined with the characteristics of chaotic sequence. This method improves the anti-interception performance of satellite communication system and has a good application prospect.
