Optimizing non-orthogonal multiple access (NOMA) in multi-cell scenarios is much more
challenging than the single-cell case because inter-cell interference must be considered …

In this study, we establish connections between asymptotic functions and properties of
solutions to important problems in wireless networks. We start by introducing a class of self …

Many common instances of power control problems for cellular and cell-free massive MIMO
networks can be interpreted as max-min utility optimization problems involving affine …

In this technical note, we present a new theoretical result for multi-cell non-orthogonal
multiple access (NOMA). For multi-cell scenarios, a so-called load-coupling model has been …

We use fixed point theory to analyze nonnegative neural networks, which we define as
neural networks that map nonnegative vectors to nonnegative vectors. We first show that …

We establish necessary and sufficient conditions for a network configuration to provide
utilities that are both fair and efficient in a well-defined sense. To cover as many applications …

Solutions to network optimization problems have greatly benefited from developments in
nonlinear analysis, and, in particular, from developments in convex optimization. A key …
