Optimal Power Allocation for Amplify-And-Forward Relay Networks via Conic Programming
— Relay power allocation has been shown to provide substantial performance gain in wireless relay channels when perfect global channel state information (CSI) is available. In th...

Limited feedback achieves the empirical capacity
The utility of limited feedback for coding over an individual sequence of DMCs is investigated. This study complements recent results showing how limited or noisy feedback can boo...

Feedback Capacity of Stationary Sources over Gaussian Intersymbol Interference Channels
Abstract— We consider discrete-time channels with finitelength intersymbol interference and additive Gaussian noise. The channel noise is considered to be a stationary ARMA (aut...
