Multi-stream Transmission for Directional Modulation Network via distributed Multi-UAV-aided Multi-IRS

arXiv:2404.15297v1 Announce Type: cross
Abstract: Active intelligent reflecting surface (IRS) is a revolutionary technique for the future 6G networks. The conventional far-field single-IRS-aided directional modulation(DM) networks have only one (no direct path) or two (existing direct path) degrees of freedom (DoFs). This means that there are only one or two streams transmitted simultaneously from base station to user and will seriously limit its rate gain achieved by IRS. How to create multiple DoFs more than two for DM? In this …
