Aircraft with a supersonic speed has a complex flow field around its optical window. The
precise modeling of the refractive index of the flow field is of great significance for the …

Stochastic digital backpropagation (SDBP) is an extension of digital backpropagation (DBP)
and is based on the maximum a posteriori principle. SDBP takes into account noise from the …

The impairments arising from the Kerr nonlinearity in optical fiber are a major obstacle in
fiber-optic transmission systems. To compensate for these impairments at the receiver, the …

Fiber nonlinearity compensation (NLC) is likely to become an indispensable component of
