A de Bruijn identity for discrete random variables
Oliver Johnson, Saikat Guha
We discuss properties of the "beamsplitter addition" operation, which provides a non-standard scaled convolution of random variables supported on the non-negative integers. We give…
Covert Single-hop Communication in a Wireless Network with Distributed Artificial Noise Generation
Ramin Soltani, Boulat Bash, Dennis Goeckel +2
Covert communication, also known as low probability of detection (LPD) communication, prevents the adversary from knowing that a communication is taking place. Recent work has demo…
Thinning, photonic beamsplitting, and a general discrete entropy power inequality
Saikat Guha, Jeffrey H. Shapiro, Raul Garcia-Patron Sanchez
Many partially-successful attempts have been made to find the most natural discrete-variable version of Shannon's entropy power inequality (EPI). We develop an axiomatic framework…
Covert Optical Communication
Boulat A. Bash, Andrei H. Gheorghe, Monika Patel +4
Encryption prevents unauthorized decoding, but does not ensure stealth---a security demand that a mere presence of a message be undetectable. We characterize the ultimate limit of…
Coded Distributed Diversity: A Novel Distributed Reception Technique for Wireless Communication Systems
Junil Choi, David J. Love, Patrick Bidigare
In this paper, we consider a distributed reception scenario where a transmitter broadcasts a signal to multiple geographically separated receive nodes over fading channels, and eac…
Superadditivity of Quantum Channel Coding Rate with Finite Blocklength Joint Measurements
Hye Won Chung, Saikat Guha, Lizhong Zheng
The maximum rate at which classical information can be reliably transmitted per use of a quantum channel strictly increases in general with , the number of channel outputs that…
