Abstract
En 中文
A new directional modulation system that 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.
