Quantization using Compressive Sensing
Rajiv Soundararajan, Sriram Vishwanath
The problem of compressing a real-valued sparse source using compressive sensing techniques is studied. The rate distortion optimality of a coding scheme in which compressively sen…
Network Coding for Multiple Unicasts: An Interference Alignment Approach
Abhik Das, Sriram Vishwanath, Syed Jafar +1
This paper considers the problem of network coding for multiple unicast connections in networks represented by directed acyclic graphs. The concept of interference alignment, tradi…
Network Control: A Rate-Distortion Perspective
Jubin Jose, Sriram Vishwanath
Today's networks are controlled assuming pre-compressed and packetized data. For video, this assumption of data packets abstracts out one of the key aspects - the lossy compression…
Sum Capacity of K User Gaussian Degraded Interference Channels
Jubin Jose, Sriram Vishwanath
This paper studies a family of genie-MAC (multiple access channel) outer bounds for K-user Gaussian interference channels. This family is inspired by existing genie-aided bounding…
Distributed Rate Allocation for Wireless Networks
Jubin Jose, Sriram Vishwanath
This paper develops a distributed algorithm for rate allocation in wireless networks that achieves the same throughput region as optimal centralized algorithms. This cross-layer al…
On Achievable Rates for Non-Linear Deterministic Interference Channels
Amin Jafarian, Sriram Vishwanath
This paper extends the literature on interference alignment to more general classes of deterministic channels which incorporate non-linear input-output relationships. It is found t…
Information Theoretic Bounds for Low-Rank Matrix Completion
Sriram Vishwanath
This paper studies the low-rank matrix completion problem from an information theoretic perspective. The completion problem is rephrased as a communication problem of an (uncoded)…
On the Vacationing CEO Problem: Achievable Rates and Outer Bounds
Rajiv Soundararajan, Aaron B. Wagner, Sriram Vishwanath
This paper studies a class of source coding problems that combines elements of the CEO problem with the multiple description problem. In this setting, noisy versions of one remote…
