The source coding game with a cheating switcher
Hari Palaiyanur, Cheng Chang, Anant Sahai
Motivated by the lossy compression of an active-vision video stream, we consider the problem of finding the rate-distortion function of an arbitrarily varying source (AVS) composed…
The price of ignorance: The impact of side-information on delay for lossless source-coding
Cheng Chang, Anant Sahai
Inspired by the context of compressing encrypted sources, this paper considers the general tradeoff between rate, end-to-end delay, and probability of error for lossless source cod…
Balancing forward and feedback error correction for erasure channels with unreliable feedback
Anant Sahai
The traditional information theoretic approach to studying feedback is to consider ideal instantaneous high-rate feedback of the channel outputs to the encoder. This was acceptable…
Zero-rate feedback can achieve the empirical capacity
Krishnan Eswaran, Anand D. Sarwate, Anant Sahai +1
The utility of limited feedback for coding over an individual sequence of DMCs is investigated. This study complements recent results showing how limited or noisy feedback can boos…
Sequential decoding for lossless streaming source coding with side information
Hari Palaiyanur, Anant Sahai
The problem of lossless fixed-rate streaming coding of discrete memoryless sources with side information at the decoder is studied. A random time-varying tree-code is used to seque…
What is needed to exploit knowledge of primary transmissions?
Pulkit Grover, Anant Sahai
Recently, Tarokh and others have raised the possibility that a cognitive radio might know the interference signal being transmitted by a strong primary user in a non-causal way, an…
