A Capacity Region Outer Bound for the Two-User Perturbative Nonlinear Fiber Optical Channel (2105.14964v3)
Published 31 May 2021 in cs.IT and math.IT
Abstract: 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 capacity region of simultaneously achievable rate pairs, assuming a two-user perturbative channel model.
