Designing iterative algorithms for interference alignment (IA) is very useful for both practical and theoretical purposes. However, the existing works on iterative IA algorithms have not reported significant gains in terms of the DoF (Degrees of Freedom) over simple orthogonalization schemes. In this paper, we aim to design an iterative IA algorithm that can achieve high DoF. We recast the problem...
Throughput-optimal multihop wireless network operation entails a key physical-layer optimization problem: maximizing a weighted sum of link rates, with weights given by the differential queue backlogs. This emerges in joint back-pressure routing and power control, which is central in cross-layer wireless networking. We begin by showing that the core problem is not only nonconvex, but also NP-hard...
