Automated Damage Inspection of Power Transmission Towers from UAV Images
Aleixo Cambeiro Barreiro, Clemens Seibold, Anna Hilsmann +1
Infrastructure inspection is a very costly task, requiring technicians to access remote or hard-to-reach places. This is the case for power transmission towers, which are sparsely…
Capacity Region Bounds for the K user Dispersive Nonlinear Optical WDM Channel with Peak Power Constraints
Viswanathan Ramachandran, Gabriele Liga, Astrid Barreiro +1
It is known that fiber nonlinearities induce crosstalk in a wavelength division multiplexed (WDM) system, which limits the capacity of such systems as the transmitted signal power…
A Data-driven Optimization of First-order Regular Perturbation Coefficients for Fiber Nonlinearities
Astrid Barreiro, Gabriele Liga, Alex Alvarado
We study the performance of gradient-descent optimization to estimate the coefficients of the discrete-time first-order regular perturbation (FRP). With respect to numerically comp…
A Capacity Region Outer Bound for the Two-User Perturbative Nonlinear Fiber Optical Channel
Viswanathan Ramachandran, Astrid Barreiro, Gabriele Liga +1
We study a nonlinear fiber optical channel impaired by cross-phase modulation and dispersion from the viewpoint of an interference channel. We characterize an outer bound on the ca…
Modeling of Nonlinear Interference Power for Dual-Polarization 4D Formats
Gabriele Liga, Bin Chen, Astrid Barreiro +1
We assess the accuracy of a recently introduced nonlinear interference model for general dual-polarization 4D formats.~ Unlike previous models for polarization-multiplexed 2D forma…
