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 ...

Mode-Dependent Loss and Gain: Statistics and Effect on Mode-Division Multiplexing

, 2011
In multimode fiber transmission systems, mode-dependent loss and gain (collectively referred to as MDL) pose fundamental performance limitations. In the regime of strong mode coupling, the statistics of MDL (expressed in decibels or log power gain units)

Demultiplexing in mode-division multiplexing system using multichannel blind deconvolution

IEEE Photonics Journal, 2016
We propose a mode demultiplexing method based on multichannel blind deconvolution (MBD) for a mode-division multiplexing (MDM) system. A 6 $\times$ 6 MDM transmission system is simulated to verify the performance of MBD.
