NeTS: Medium: Multicell MIMO for Scalable High-Density
Wireless Networks
NSF Project Number: CNS–1513884
Project Overview
This project studied techniques for scaling wireless network performance
linearly with the number of access points in high-density network deployments.
Current wireless network performance scales only up to the number of orthogonal
channels, which is often quite a small number. This project looked to achieve
performance scaling well beyond the number of orthogonal channels through
access point cooperation and advanced signal processing techniques.
The project demonstrated significant performance increases through novel
coordinated multipoint transmission techniques and scheduling algorithms that
produce near-optimal aggregate throughput among all solutions that satisfy a
given fairness constraint. The project also demonstrated techniques for
implementing a given communication schedule across multiple APs in a dense
network using contention-based MAC protocols, which allows our cooperative
approach to be achieved without requiring a full TDMA implementation.
Finally, the project studied the application of nonlinear precoding to
handle interference at the edges of access point (AP) clusters as well as
interference between neighboring APs that is not well-managed through linear
methods.
