Delayed Frame Repetition for Free Space Optical communication (FSO) Channel
, 2017 Free space optical communication is gaining interest because of its various advantages like high data rate, high power efficiency, no license regulation etc. However, one has to overcome the challenge of distortion and fading caused by atmospheric turbulences and bad weather conditions. Free space optical communication channel is a time variant channel.

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 ...
