Robust Covert Communication over a Public Audio Channel Using Spread Spectrum
We present a set of watermarking techniques for effective covert communication over an audio signal carrier. Watermark robustness is enabled using: (i) redundant spread-spectrum fo...

Mutual Information of MIMO Transmission over Correlated Channels with Finite Symbol Alphabets and Link Adaptation
In this paper, results on the mutual information of MIMO transmission over spatially correlated channels in slow fading environments are presented. Different receiver techniques su...

Building Covert Channels over the Packet Reordering Phenomenon
Abstract—New modes of communication have shown themselves to be needed for more secure and private types of data. Steganography or data-hiding through covert channels can be high...

On Communication over Unknown Sparse Frequency-Selective Block-Fading Channels
The problem of reliable communication over unknown frequency-selective block-fading channels with sparse impulse responses is considered. In particular, discrete-time impulse respo...

Bounds and algorithms for time delay estimation on parallel, flat fading channels
We study time delay estimation (TDE) on parallel channels with flat fading. Several models for the channel gains are considered, and for each case we present the the maximum like...
