Study on anti-jamming communication technology based on transform domain

摘要

Based on transform domain, this paper presents the research about anti-jamming communication technology. Firstly, it demonstrates the basic principle of transform domain communication system (TDCS), in which message is modulated depending on a kind of basic noise-like function to improve its concealment. Then, Based on two-dimension time-frequency design, a communication system with transform domain and multiple users is proposed. By constructing sequence having perfect/quasi-perfect cross-correlation characteristics, this system can eliminate or reduce the interference among multiple users. Finally, the simulation result indicates that this method can effectively solve the problems of active anti-jamming.
