Degrees of Freedom of Multi-hop MIMO Broadcast Networks with Delayed CSIT
Zhao Wang, Ming Xiao, Chao Wang +1
We study the sum degrees of freedom (DoF) of a class of multi-layer relay-aided MIMO broadcast networks with delayed channel state information at transmitters (CSIT). In the assume…
Analysis of MMSE Estimation for Compressive Sensing of Block Sparse Signals
Mikko Vehkaperä, Saikat Chatterjee, Mikael Skoglund
Minimum mean square error (MMSE) estimation of block sparse signals from noisy linear measurements is considered. Unlike in the standard compressive sensing setup where the non-zer…
Secret Key Agreement Using Correlated Sources over the Generalized Multiple Access Channel
Somayeh Salimi, Mikael Skoglund
A secret key agreement setup between three users is considered in which each of the users 1 and 2 intends to share a secret key with user 3 and users 1 and 2 are eavesdroppers with…
Analysis of Sparse Representations Using Bi-Orthogonal Dictionaries
Mikko Vehkaperä, Yoshiyuki Kabashima, Saikat Chatterjee +3
The sparse representation problem of recovering an N dimensional sparse vector x from M < N linear observations y = Dx given dictionary D is considered. The standard approach is to…
Coding With Action-dependent Side Information and Additional Reconstruction Requirements
Kittipong Kittichokechai, Tobias J. Oechtering, Mikael Skoglund
Constrained lossy source coding and channel coding with side information problems which extend the classic Wyner-Ziv and Gel'fand-Pinsker problems are considered. Inspired by appli…
Successive Secret Key Agreement over Generalized Multiple Access and Broadcast Channels
Somayeh Salimi, Mikael Skoglund, Mahmoud Salmasizadeh +1
A secret key agreement framework between three users is considered in which each of the users 1 and 2 intends to share a secret key with user 3 and users 1 and 2 are eavesdroppers…
