Operational Capacity and Pseudoclassicality of a Quantum Channel
We explore some basic properties of coding theory of a general quantum communication channel and its operational capacity, including (1) adaptive measurement with feedback code, (...

Outer Bounds for Multiple Access Channels with Feedback using Dependence Balance
We use the idea of dependence balance to obtain a new outer bound for the capacity region of the discrete memoryless multiple-access channel with noiseless feedback (MAC-FB). We co...

A Feedback Reduction Technique for MIMO Broadcast Channels
A multiple antenna broadcast channel with perfect channel state information at the receivers is considered. If each receiver quantizes its channel knowledge to a finite number of b...

Stabilization using both noisy and noiseless feedback
Abstract-- When designing a distributed control system, the system designer has a choice in how to connect the different units through communication channels. In practice, noiseles...
