Abstract :
A method of mitigating the effects of packaging on secure communications using directional modulation has been demonstrated. While this work used LOS communications, it can be easily generalized to non-line-of-sight channels with multipath. The procedure used to determine the sets of phase shifts for DM is applicable to arbitrarily-spaced arrays using any variety of quadrature amplitude modulation.
