Channel characterization and empirical model for ergodic capacity of free-space optical communication link
Isiaka A. Alimi,Ali Shahpari,Vitor Ribeiro,Artur Sousa,Paulo P. Monteiro,Antônio Lúcio Teixeira +5 more
TL;DR: Experimental results on channel characterization of single input single output (SISO) free-space optical (FSO) communication link that is based on channel measurements are presented and a closed-form expression for determining ergodic channel capacity of multiple input multiple output (MIMO) FSO communication systems over atmospheric turbulence fading channels is proposed.

Optical performance monitoring using the novel parametric asynchronous eye diagram
TL;DR: A simulation scheme, which includes a differentiator and an Artificial Neural Network to monitor simultaneously several impairments such as Chromatic Dispersion, Polarization Mode Dispersion and Optical Signal to Noise Ratio is used.

Joint Iterative Carrier Synchronization and Signal Detection Employing Expectation Maximization
Darko Zibar,Luis H. H. Carvalho,Jose Estaran,Edson Porto da Silva,Carolina Franciscangelis,Vitor Ribeiro,Robert Borkowski,Ole Winther,Mikkel N. Schmidt,Julio C. R. F. Oliveira,Idelfonso Tafur Monroy +10 more
TL;DR: It is shown that joint carrier synchronization and data detection are more robust towards optical transmitter impairments and nonlinear phase noise, compared to digital phase-locked loop (PLL) followed by hard decisions.
