Green Codes: Energy-Efficient Short-Range Communication
Pulkit Grover, Anant Sahai
A green code attempts to minimize the total energy per-bit required to communicate across a noisy channel. The classical information-theoretic approach neglects the energy expended…
The price of certainty: "waterslide curves" and the gap to capacity
Anant Sahai, Pulkit Grover
The classical problem of reliable point-to-point digital communication is to achieve a low probability of error while keeping the rate high and the total power consumption small. T…
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…
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…
