Two‐Way Relaying for Orbital Angular Momentum LOS Transmission
International Journal of Communication Systems, Volume 38, Issue 13, 10 September 2025.This paper investigates two‐way relaying (TWR) for orbital angular momentum (OAM)‐based line‐of‐sight (LOS) transmission. Low‐complexity near‐ML detectors are proposed for OAM mode division multiplexing and index modulation. Theoretical analysis and simulations confirm that TWR significantly improves bit error performance and spectral efficiency over ...
