Channel and Multiuser Diversities in Wireless Systems: Delay-Energy Tradeoff
We consider a communication system with multi-access fading channel. Each user in the system requires certain rate guarantee. Our main contribution is to devise a scheduling scheme...

Optimizing Zero-Forcing Based Gain Allocation for Wireless Multiuser Networks
— We consider a wireless multiuser network where a number of source/destination pairs communicate concurrently over the same physical channel. A set of amplify-and-forward relay ...
