Directional Modulation Design Under a Constant Magnitude Constraint for Weight Coefficients

Directional Modulation Design Under a Constant Magnitude Constraint for Weight Coefficients

Directional modulation (DM) as a physical layer security technique has been studied from many different aspects recently. Normally all existing designs based on antenna arrays lead to varying weight coefficients for different antennas and for different signal symbols, which poses a particular challe...
