Modulation and Signal Processing for LEO-LEO Optical Inter-satellite Links

I. P. Vieira, T. C. Pita, D. A. A. Mello

We investigate key aspects of coherent optical communications on inter-satellite links (ISLs) for the next-generation ultra-dense low-Earth orbit (LEO) constellations. Initially, t…

MDG and SNR Estimation in SDM Transmission Based on Artificial Neural Networks

Ruby S. B. Ospina, Menno van den Hout, Sjoerd van der Heide +7

The increase in capacity provided by coupled SDM systems is fundamentally limited by MDG and ASE noise. Therefore, monitoring MDG and optical SNR is essential for accurate performa…

Neural-network-based MDG and Optical SNR Estimation in SDM Transmission

Ruby S B Ospina, Menno van den Hout, Sjoerd van der Heide +2

We propose a neural network model for MDG and optical SNR estimation in SDM transmission. We show that the proposed neural-network-based solution estimates MDG and SNR with high ac…

Experimental validation of MDL emulation and estimation techniques for SDM transmission systems

Menno van den Hout, Ruby S. B. Ospina, Sjoerd van der Heide +8

We experimentally validate a mode-dependent loss (MDL) estimation technique employing acorrection factor to remove the MDL estimation dependence on the SNR when using a minimum mea…

Mode-dependent Loss and Gain Estimation in SDM Transmission Based on MMSE Equalizers

Ruby S. B. Ospina, Menno van den Hout, Juan Carlos Alvarado-Zacarias +7

The capacity in space division multiplexing (SDM) systems with coupled channels is fundamentally limited by mode-dependent loss (MDL) and mode-dependent gain (MDG) generated in com…

Interplay of Probabilistic Shaping and the Blind Phase Search Algorithm

Darli A. A. Mello, Fabio A. Barbosa, Jacklyn D. Reis

Probabilistic shaping (PS) is a promising technique to approach the Shannon limit using typical constellation geometries. However, the impact of PS on the chain of signal processin…
