摘要: In this study, a far-field power pattern separation approach is proposed for the synthesis of directional modulation (DM) transmitter arrays. Separation into information patterns and interference enabled by null steering. Compared with other DM methods, example, bit error rate-driven optimisation orthogonal vector injection, developed in study facilitates manipulation artificial spatial distributions. With such capability more can be projected those directions most vulnerable to eavesdropping, that is, side lobes. fashion, leaked through radiation lobes effectively mitigated efficient manner. Furthermore, first time, authors demonstrate how multi-beam transmitters synthesised via approach.
