Differential feedback of MIMO channel correlation matrices based on geodesic curves
This paper proposes a differential quantization strategy to be used in the feedback link of a multi-input-multi-output (MIMO) communication system. This algorithm is applied to th...

MIMO Multiple Access Channels with Noisy Channel Estimation and Partial CSI Feedback
Abstract—We consider correlated MIMO multiple access channels with block fading, where each block is divided into training and data transmission phases. We find the channel esti...

End-to-end versus explicit feedback measurement in 802.11 networks
Higher layer protocols in wireless networks need to dynamically adapt to observed network response. The common approach is that each session employs end-to-end monitoring to estim...

Data masking: a secure-covert channel paradigm
— It is well known that encryption provides secure channels for communicating entities. However, due to lack of covertness on these channels, an eavesdropper can identify encrypt...

The Impact of Stochastic Noisy Feedback on Distributed Network Utility Maximization
—The implementation of distributed network utility maximization (NUM) algorithms hinges heavily on information feedback through message passing among network elements. In practic...
