Channel quantization design in multiuser MIMO systems: Asymptotic versus practical conclusions
Feedback of channel state information (CSI) is necessary to achieve high throughput and low outage probability in multiuser multiantenna systems. There are two types of CSI: direc...

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...

Coding Strategies for Bidirectional Relaying for Arbitrarily Varying Channels
In this work we study optimal coding strategies for bidirectional relaying under the condition of arbitrarily varying channels. We consider a three-node network where a relay node ...

The role of channel states in secret key generation
In this work, we investigate secret key generation from channel states. We point out, by means of a packet-delaybased attack, that observing its own channel states is not the only ...
