Uplink-Downlink Duality in Normalized MSE or SINR Under Imperfect Channel Knowledge
Abstract— Duality between the multi-antenna multi-user uplink and the downlink has been discovered in terms of sum rate, capacity region, signal-to-interference-plus-noise-ratio ...

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...

Conceptual Neighborhoods for Retrieval in Case-Based Reasoning
Abstract. We present a case-based reasoning technique based on conceptual neighborhoods of cases. The system applies domain knowledge to the case retrieval process in the form of r...

Case-Based Reasoning for Build Order in Real-Time Strategy Games
We present a case-based reasoning technique for selecting build orders in a real-time strategy game. The case retrieval process generalizes features of the game state and selects ...

A MIMO channel perturbation analysis for robust bit loading
In narrowband multiple-input multiple-output (MIMO) communication systems, when the channel state information (CSI) is known perfectly at the transmitter and the receiver, techniq...
