Optimal Selective Feedback Policies for Opportunistic Beamforming
Tharaka Samarasinghe, Hazer Inaltekin, Jamie S. Evans
This paper studies the structure of downlink sum-rate maximizing selective decentralized feedback policies for opportunistic beamforming under finite feedback constraints on the av…
On the Tradeoff Between Multiuser Diversity and Training Overhead in Multiple Access Channels
Jonathan Scarlett, Jamie Evans, Subhrakanti Dey
We consider a single antenna narrowband multiple access channel in which users send training sequences to the base station and scheduling is performed based on minimum mean square…
Vector Broadcast Channels: Optimal Threshold Selection Problem
Tharaka Samarasinghe, Hazer Inaltekin, Jamie Evans
Threshold feedback policies are well known and provably rate-wise optimal selective feedback techniques for communication systems requiring partial channel state information (CSI).…
Vector Broadcast Channels: Optimality of Threshold Feedback Policies
Tharaka Samarasinghe, Hazer Inaltekin, Jamie Evans
Beamforming techniques utilizing only partial channel state information (CSI) has gained popularity over other communication strategies requiring perfect CSI thanks to their lower…
