On successive refinement of diversity for fading ISI channels
S. Dusad, S. N. Diggavi
Rate and diversity impose a fundamental trade-off in communications. This trade-off was investigated for flat-fading channels in [15] as well as for Inter-symbol Interference (ISI)…
Asymmetric Multilevel Diversity Coding and Asymmetric Gaussian Multiple Descriptions
Soheil Mohajer, Chao Tian, Suhas N. Diggavi
We consider the asymmetric multilevel diversity (A-MLD) coding problem, where a set of information sources, ordered in a decreasing level of importance, is encoded into …
Secret-Key Generation using Correlated Sources and Channels
Ashish Khisti, Suhas Diggavi, Gregory Wornell
We study the problem of generating a shared secret key between two terminals in a joint source-channel setup -- the sender communicates to the receiver over a discrete memoryless w…
Wireless Network Information Flow: A Deterministic Approach
Salman Avestimehr, Suhas Diggavi, David Tse
In a wireless network with a single source and a single destination and an arbitrary number of relay nodes, what is the maximum rate of information flow achievable? We make progres…
Approximate Characterizations for the Gaussian Source Broadcast Distortion Region
Chao Tian, Suhas Diggavi, Shlomo Shamai
We consider the joint source-channel coding problem of sending a Gaussian source on a K-user Gaussian broadcast channel with bandwidth mismatch. A new outer bound to the achievable…
