Two-dimensional and high-order directional information modulations for secure communications based on programmable metasurface
Abstract Conventional wireless communication schemes indiscriminately transmit information into the whole space and pose inherent security risks. Recently, directional information modulation (DIM) has attracted enormous attention as a promising technology. DIM generates correct constellation symbols...
