Power-controlled feedback and training for two-way MIMO channels
Most communication systems use some form of feedback, often related to channel state information. The common models used in analyses either assume perfect channel state information...

Combining Beamforming and Space-Time Coding Using Noisy Quantized Feedback
The goal of combining beamforming and space-time coding is to obtain full-diversity order and to provide additional received power (array gain) compared to conventional space-time...

Suboptimal decentralized control over noisy communication channels
In this paper we present a technique for design of decentralized controllers for mean square stability of a large scale system with cascaded clusters of subsystems. Each subsystem...

An Achievable Rate Region for the Broadcast Channel with Feedback
A single-letter achievable rate region is proposed for the two-receiver discrete memoryless broadcast channel with noiseless or noisy feedback. The coding strategy involves block-...

How to beat the sphere-packing bound with feedback
The sphere-packing bound Esp(R) bounds the reliability function for fixed-length block-codes. For symmetric channels, it remains a valid bound even when strictly causal noiseless ...
