Optimization of AMI-MDM-RoFSO under atmospheric turbulence

Abstract

Abstract. Radio over Free Space (Ro-FSO) is promising candidate for providing ubiquitous digital services especially in rural areas. This work investigates the performance of MDM of two 5Gbps-10GHz data channels over FSO link using LP 01 and LP 02 modes under the effect of atmospheric turbulences. The signal to noise ratio (SNR), total received power, modal decomposition at receiver at the receiver is also reported. The reported result shows the successful transmission of two channels with acceptable SNR over FSO link under atmospheric turbulences.

Enhanced performance analysis of a hybrid spectrum sliced‐wavelength division multiplexing‐mode division multiplexing‐orthogonal frequency division multiplexing based radio‐over‐free space optics

“…The authors in Refs. report the performance analysis of MDM based Ro‐FSO link under the impact of different environmental conditions and beam divergence. In this paper, we propose modeling and simulative investigation of hybrid spectrum‐sliced wavelength division multiplexing‐mode division multiplexing (SS‐WDM‐MDM) based OFDM‐Ro‐FSO transmission link.…”

Radio-over-free space optical space division multiplexing system using 3-core photonic crystal fiber mode group multiplexers

“…Space division multiplexing (SDM) is a recent spatial diversity strategy transpired by utilizing different eigenmodes in optical fiber as independent channels to create multiple-input-multiple-output systems [22][23][24][25][26][27]. SDM enables the provision of multiple links during harsh weather conditions in case of failure of any of the links and increases the achievable link distance [28][29][30][31][32][33][34].…”
