A hybrid scheme for wireless physical layer security based on encryption and channel pre-compensation

In this paper, a new hybrid scheme for physical layer security based on encryption and wireless channel pre-compensation is proposed. The security is provided by transforming the basic signal constellation into a higher order signal constellation with the help of conventional encryption m...
