A Two-Ray Multipath Model for Frequency Diverse Array-Based Directional Modulation in MISOME Wiretap Channels
A two-ray multipath model for frequency diverse array (FDA)-based directional
modulation (DM) is proposed in multi-input single-output multi-eavesdropper
(MISOME) wiretap channels for the first time. The excitation factors of the FDA
and the weighting coefficients of the inserted artificial noise (AN) are
jointly designed in a way which imposes no impact on the desired receiver while
simultaneously distorting the received signals of eavesdroppers. Secrecy rate
is analyzed for the proposed two-ray multipath FDA-based DM model. Numerical
simulations verify the capability of physical layer secure (PLS) transmissions
of the proposed FDA-DM model in two-ray multipath MISOME wiretap channels.Comment: accepted by IEEE VTC2019-Fall, 5 pages, 6 figure
