Capacity Bounds for Optical WDM Channels with Peak Power Constraints
Viswanathan Ramachandran, Gabriele Liga, Astrid Barreiro +1
We investigate optical WDM transmission from the standpoint of an information-theoretic interference channel. Achievable rates that outperform treating interference as noise are pr…

A Capacity Region Outer Bound for the Two-User Perturbative Nonlinear Fiber Optical Channel
Viswanathan Ramachandran, Astrid Barreiro, Gabriele Liga +1
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 ca…

Joint State Estimation and Communication over a State-Dependent Gaussian Multiple Access Channel
Viswanathan Ramachandran, Sibi Raj B Pillai, Vinod M Prabhakaran
A hybrid communication network with a common analog signal and an independent digital data stream as input to each node in a multiple access network is considered. The receiver/bas…
