Low-delay scheduling for Grassmannian beamforming with a SINR constraint
We are presenting an algorithm for scheduling users in a single-cell broadcast scenario. The presented algorithm aims to minimize the number of transmissions that are necessary to...

Bandwidth Efficient All-to-All Broadcast on Switched Clusters
We develop an all-to-all broadcast scheme that achieves maximum bandwidth efficiency for clusters with tree topologies. Using our scheme for clusters with cut-through switches, an...

Nested Partitioning for the Minimum Energy Broadcast Problem
The problem of finding the broadcast scheme with minimum power consumption in a wireless ad-hoc network is NP-hard. This work presents a new hybrid algorithm to solve this problem...

Coordinated beamforming with limited feedback in the MIMO broadcast channel
In this paper, we propose a new joint optimization of linear transmit beamforming and receive combining vectors for the multiple-input multiple-output (MIMO) broadcast channel. We ...
