Soft Demapping of Spherical Codes from Cartesian Powers of PAM Constellations
Reza Rafie Borujeny, Susanna E. Rumsey, Stark C. Draper +1
For applications in concatenated coding for optical communications systems, we examine soft-demapping of short spherical codes constructed as constant-energy shells of the Cartesia…
Why Constant-Composition Codes Reduce Nonlinear Interference Noise
Reza Rafie Borujeny, Frank Kschischang
A time-domain perturbation model of the nonlinear Schrodinger equation is used to study wavelength-division multiplexed communication over a single polarization. The model explains…
Channel Matching: An Adaptive Technique to Increase the Accuracy of Soft Decisions
Reza Rafie Borujeny, Frank R. Kschischang
Nonlinear interference is modeled by a time-varying conditionally Gaussian channel. It is shown that approximating this channel with a time-invariant channel imposes considerable l…
A Signal-Space Distance Measure for Nondispersive Optical Fiber
Reza Rafie Borujeny, Frank R. Kschischang
The nondispersive per-sample channel model for the optical fiber channel is considered. Under certain smoothness assumptions, the problem of finding the minimum amount of noise ene…
