The Entropy of Floating-Point Numbers
Sultan M. Daniels, Samuel H. D'Ambrosia, Michael R. DeWeese +1
Here we present an analytic approximation for the entropy of floating-point numbers, along with bounds on the error of this approximation. It is well-known that the differential en…
Wireless Channel Dynamics and Robustness for Ultra-Reliable Low-Latency Communications
Vasuki Narasimha Swamy, Paul Rigge, Gireeja Ranade +2
Interactive, immersive and critical applications demand ultra-reliable low-latency communication (URLLC). To build wireless communication systems that can support these application…
Network Coding for Real-time Wireless Communication for Automation
Vasuki Narasimha Swamy, Paul Rigge, Gireeja Ranade +2
Real-time applications require latencies on the order of a millisecond with very high reliabilities, paralleling the requirements for high-performance industrial control. Current w…
Layered black-box, behavioral interconnection perspective and applications to the problem of communication with fidelity criteria, Part II: stationary sources satisfying ψ-mixing criterion
Mukul Agarwal, Sanjoy Mitter, Anant Sahai
Theorems from Part 1 of this paper are generalized to ψ-mixing sources in this paper. Application to Markoff chains and order m Markoff chains is presented. The main result is the…
Layered black-box, behavioral interconnection perspective and applications to the problem of communication with fidelity criteria, Part I: i.i.d. sources
Mukul Agarwal, Sanjoy Mitter, Anant Sahai
In this paper, the problem of communication over an essentially unknown channel, which is known to be able to communicate a source to a destination to within a certain distortion l…
Control Capacity
Gireeja Ranade, Anant Sahai
Feedback control actively dissipates uncertainty from a dynamical system by means of actuation. We develop a notion of "control capacity" that gives a fundamental limit (in bits) o…
Real-time Cooperative Communication for Automation over Wireless
Vasuki Narasimha Swamy, Sahaana Suri, Paul Rigge +4
High-performance industrial automation systems rely on tens of simultaneously active sensors and actuators and have stringent communication latency and reliability requirements. Cu…
Information embedding and the triple role of control
Pulkit Grover, Aaron B. Wagner, Anant Sahai
We consider the problem of information embedding where the encoder modifies a white Gaussian host signal in a power-constrained manner to encode a message, and the decoder recovers…
A universal, operational theory of unicast multi-user communication with fidelity criteria
Mukul Agarwal, Sanjoy Mitter, Anant Sahai
This is a three part paper. Optimality of source-channel separation for communication with a fidelity criterion when the channel is compound as defined by Csiszar and Korner in the…
Implicit and explicit communication in decentralized control
Pulkit Grover, Anant Sahai
There has been substantial progress recently in understanding toy problems of purely implicit signaling. These are problems where the source and the channel are implicit -- the mes…
Towards a communication-theoretic understanding of system-level power consumption
Pulkit Grover, Kristen Ann Woyach, Anant Sahai
Traditional communication theory focuses on minimizing transmit power. However, communication links are increasingly operating at shorter ranges where transmit power can be signifi…
Is Witsenhausen's counterexample a relevant toy?
Pulkit Grover, Anant Sahai
This paper answers a question raised by Doyle on the relevance of the Witsenhausen counterexample as a toy decentralized control problem. The question has two sides, the first of w…
Information embedding meets distributed control
Pulkit Grover, Aaron B. Wagner, Anant Sahai
We consider the problem of information embedding where the encoder modifies a white Gaussian host signal in a power-constrained manner to encode the message, and the decoder recove…
The finite-dimensional Witsenhausen counterexample
Pulkit Grover, Se Yong Park, Anant Sahai
Recently, a vector version of Witsenhausen's counterexample was considered and it was shown that in that limit of infinite vector length, certain quantization-based control strateg…
Equivalence perspectives in communication, source-channel connections and universal source-channel separation
Mukul Agarwal, Anant Sahai, Sanjoy Mitter
An operational perspective is used to understand the relationship between source and channel coding. This is based on a direct reduction of one problem to another that uses random…
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 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…
