A robust asynchronous multiuser STBC-OFDM transmission scheme for frequency-selective channels
Abstract--In this paper, we propose a robust STBC transmission scheme to combat timing synchronization errors over frequency-selective multiple-access channels. We start by derivin...

Robust rate control for integrated services packet networks
Abstract--Research on congestion-control algorithms has traditionally focused more on performance than on robustness of the closed-loop system to changes in network conditions. As ...

Robust Beamforming for Security in MIMO Wiretap Channels with Imperfect CSI
—In this paper, we investigate methods for reducing the likelihood that a message transmitted between two multiantenna nodes is intercepted by an undetected eavesdropper. In part...
