Secure Antenna Subset Modulation with Coordinate Interleaved Orthogonal Designs

This paper presents a secure MISO wireless transmission scheme based on a combination of the random Antenna Subset Modulation (ASM) scheme and Coordinate Interleaved Orthogonal Designs (CIOD). The combination is judiciously chosen to supplement the deficiency of ASM scheme on Rayleigh channel. It will be shown that on one hand, the proposed scheme enjoys both diversity and array gains. On the other hand, we will show that secure communication between legitimate parties is guaranteed against potential eavesdropping.
