Tight Capacity Bounds for Indoor Visible Light Communications With Signal-Dependent Noise

Capacity Bounds for the Two-User IM/DD Interference Channel

The bounds provide tight and easily computable inner and outer bounds for a general two-user IM/DD IC under peak and average optical intensity constraints, which enable characterizing the asymptotic sum-rate capacity in the strong and weak interference regimes, as well as the generalized degrees of freedom (GDoF) in the symmetric case.

Optimal Power Allocation for Integrated Visible Light Positioning and Communication System With a Single LED-Lamp

Robust Power Allocation for Integrated Visible Light Positioning and Communication Networks

A robust power allocation scheme for integrated VLPC Networks is proposed by exploiting the intrinsic relationship between positioning and communications, and conservatively transforms the chance constraints to deterministic forms by using the Bernstein-type inequality and the conditional value-at-risk for the Gaussian and arbitrary distributed positioning errors.
