非相关切换天线扩频方向调制物理层安全传输
Spread spectrum directional modulation method based on the irrelevantly switched antenna for physical layer security transmission
摘要
Abstract
In order to improve the security of wireless communication, a spread spectrum directional modulation method based on the irrelevantly switched antenna is presented.First, the security vulnerabilities of the existing spread spectrum directional modulation method are analyzed, indicating that the existing method has the risk of security leakage in some particular directions.Then by locating the security vulnerabilities of the existing method, a security-enhanced method is proposed by separating the antenna switching from the spectrum spreading to eliminate the security vulnerabilities.Finally, the physical layer security performance of two directional modulation methods is simulated, with the results showing that the proposed method has a better low detection performance and anti-jamming capability.关键词
