Enhancing FSO‐DWDM Performance Through Compensation Strategies

Engineering Reports, Volume 7, Issue 12, December 2025.
This study investigates the performance of free space optics (FSO) with dense wavelength division multiplexing (DWDM) systems, focusing on the impact of channel number and compensation strategies on bit error rate (BER). Results show that post‐compensation significantly improves performance, extending the system's range from 3 to 5 km.

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 ...
