How to statistically model coherent MPI in optical communications? [PDF]

, 2018
The Beta distribution is used to model coherent MPI in optical communications and its fitness to describe experimental results is evaluated. It fits quite well to symmetric scenarios, but has some troubles when skewness matters.info:eu-repo/semantics ...

Comparison of ICI Reduction and Fiber Nonlinearity Tolerance for DCS-OFDM and Conventional OFDM With Equal Spectrum Efficiency

IEEE Photonics Journal, 2015
Digital coherent superposition (DCS) for optical orthogonal frequency-division multiplexing (OFDM) subcarrier pairs with Hermitian symmetry can simultaneously reduce the inter-carrier interference (ICI) from laser phase noise and cancel the fiber ...

Stochastic Backpropagation for Coherent Optical Communications [PDF]

, 2011
We present stochastic backpropagation, a novel maximum a posteriori detection method for coherent optical communication. The proposed detector is shown to outperform conventional backpropagation in a scenario where nonlinear phase noise is the dominant ...

Lambertian source modelling of free space optical ground-to-train communications [PDF]

, 2012
There is a increasing demand for high speed data services while travelling on trains and other means of public transportation. Hence, an alternative technology to radio frequency (RF) communications called free space optics (FSO) could be used to provide
