SINR Balancing for the Multi-User Downlink under General Power Constraints
Abstract—We address the problem of maximizing the minimum signal to interference and noise ratio of individual users via linear precoding in a multiuser downlink channel with mul...

MIMO transceiver optimization with linear constraints on transmitted signal covariance components
Abstract--This correspondence revisits the joint transceiver optimization problem for multiple-input multiple-output (MIMO) channels. The linear transceiver as well as the transcei...

Optimal Power Scheduling for Correlated Data Fusion in Wireless Sensor Networks via Constrained PSO
Optimal power scheduling for distributed detection in a Gaussian sensor network is addressed for both independent and correlated observations. We assume amplify-and-forward local p...

Code design for MIMO downlink with imperfect CSIT
—In this letter, we implement a simplified version of the Cover - van der Meulen - Hajek - Pursley (CMHP) coding originally characterized by Wajcer, Wiesel, and Shamai. The vect...
