“…However the proposed use of radio hardware can provide an additional layer of privacy, capable of impeding data interception. One technique investigated for this purpose is Directional Modulation (DM) [2][3][4][5][6], which in its most common implementation requires a large and bulky antenna array with a complex weighting system. Some simplification was proposed by Tao Hong et al in [6], where a two-antenna system is used with antenna ports connected directly to the I and Q outputs of the standard QAM transceiver.…”

Abstract-A new directional modulation system which uses radiation pattern data for modulation encoding is proposed. The approach allows compact multiport antennas (e.g. MIMO capable antennas) to be used for directional modulation, replacing extensive arrays. The modulation weighting coefficients are calculated with a fixed, antenna specific equation, thus reducing computational complexity. The solution is intended to enhance privacy in small, battery-operated wireless devices, required for "Internet of Things" applications.

“…It has been shown in Section A that the synthesized pattern is governed by the complex weights wx and wy, and the distances between two antenna elements (mdx and ndy) representing the relative position of each antenna element from phase center in x-y plane. The actual power patterns of symmetrically distributed uniform array elements is as given by (5). Consider now what happens when the distributed antenna elements in a given xy-plane space are mapped to a µ × ν space where:…”

“…Millimeter wave (mm-wave) technology is considered to be among the most notable candidate for the next generation communication systems because of promising features like high spectral efficiency [1], [2]. Other techniques such as beam space modulation [3]- [5] may also have a major role to play.…”

Abstract-This paper presents a novel approach to formulate an aggressively thinned sparse antenna array suitable for orthogonal multi-beam receiver applications. The power patterns of M×N element planar rectangular array are first reduced to orthogonally placed cross multiplicative sub-arrays. These arrays are then re-distributed using a compressive sensing (CS) approach in order to achieve array thinning along two 1-D sub-arrays for a fixed steered beam projection. A multi-beam synthesis approach is then implemented which permits efficient beam maxima as well as null placement of multiple interlaced far-field patterns. Numerical examples are presented to show the implementation of the proposed approach.

Abstract-By modification of the classical retrodirective arrays (RDAs) architecture a directional modulation (DM) transmitter can be realized without the need for synthesis. Importantly, through analytical analysis and exemplar simulations, it is proved that, besides the conventional DM application scenario, i.e., secure transmission to one legitimate receiver located along one spatial direction in free space, the proposed synthesis-free DM transmitter should also perform well for systems where there are more than one legitimate receivers positioned along different directions in free space, and where one or more legitimate receivers exist in a multipath environment. None of these have ever been achieved before using synthesis-free DM arrangements.Index Terms-Directional modulation (DM), information pattern, interference pattern, retrodirective array (RDA), synthesis-free.
