Heegard-Berger and Cascade Source Coding Problems with Common Reconstruction Constraints
Behzad Ahmadi, Ravi Tandon, Osvaldo Simeone +1
For the HB problem with the CR constraint, the rate-distortion function is derived under the assumption that the side information sequences are (stochastically) degraded. The rate-…
On the Feedback Capacity of the Fully Connected -User Interference Channel
Soheil Mohajer, Ravi Tandon, H. Vincent Poor
The symmetric K user interference channel with fully connected topology is considered, in which (a) each receiver suffers interference from all other (K-1) transmitters, and (b) ea…
Degrees of Freedom Region of the MIMO Interference Channel with Output Feedback and Delayed CSIT
Ravi Tandon, Soheil Mohajer, H. Vincent Poor +1
The two-user multiple-input multiple-output (MIMO) interference channel (IC) with arbitrary number of antennas at each terminal is considered and the degrees of freedom (DoF) regio…
On the Symmetric Feedback Capacity of the K-user Cyclic Z-Interference Channel
Ravi Tandon, Soheil Mohajer, H. Vincent Poor
The K-user cyclic Z-interference channel models a situation in which the kth transmitter causes interference only to the (k-1)th receiver in a cyclic manner, e.g., the first transm…
Competitive Privacy in the Smart Grid: An Information-theoretic Approach
Lalitha Sankar, Soummya Kar, Ravi Tandon +1
Advances in sensing and communication capabilities as well as power industry deregulation are driving the need for distributed state estimation in the smart grid at the level of th…
Discriminatory Lossy Source Coding: Side Information Privacy
Ravi Tandon, Lalitha Sankar, H. Vincent Poor
A lossy source coding problem is studied in which a source encoder communicates with two decoders, one with and one without correlated side information with an additional constrain…
Multi-User Privacy: The Gray-Wyner System and Generalized Common Information
Ravi Tandon, Lalitha Sankar, H. Vincent Poor
The problem of preserving privacy when a multivariate source is required to be revealed partially to multiple users is modeled as a Gray-Wyner source coding problem with K correlat…
