Joint OSNR monitoring and modulation format identification in digital coherent receivers using deep neural networks.
TLDR
We experimentally demonstrate the use of deep neural networks (DNNs) in combination with signals' amplitude histograms (AHs) for simultaneous optical signal-to-noise ratio monitoring and modulation format identification (MFI) in digital coherent receivers. Expand

Signal processing using artificial neural network for BOTDA sensor system.
TLDR
We experimentally demonstrate the use of artificial neural network (ANN) to process sensing signals obtained from Brillouin optical time domain analyzer (BOTDA) and obtain temperature distribution along the fiber, especially when large frequency scanning step is adopted to significantly reduce the measurement time but without sacrifice of sensing accuracy.
