The First and Second-Order Asymptotics of Covert Communication over AWGN Channels
Xinchun Yu, Shuangqing Wei, Shao-Lun Huang +1
This paper investigates the asymptotics of the maximal throughput of communication over AWGN channels by channel uses under a covert constraint in terms of an upper bound o…
Total Variation Distance Based Performance Analysis of Covert Communication over AWGN Channels in Non-asymptotic Regime
Xinchun Yu, Shuangqin Wei, Yuan Luo
This paper investigates covert communication over an additive white Gaussian noise (AWGN) channel in finite block length regime on the assumption of Gaussian codebooks. We first re…
Efficient, Effective and Well Justified Estimation of Active Nodes within a Cluster
Md Mahmudul Hasan, Shuangqing Wei, Ramachandran Vaidyanathan
Reliable and efficient estimation of the size of a dynamically changing cluster in an IoT network is critical in its nominal operation. Most previous estimation schemes worked with…
Latent Factor Analysis of Gaussian Distributions under Graphical Constraints
Md Mahmudul Hasan, Shuangqing Wei, Ali Moharrer
We explore the algebraic structure of the solution space of convex optimization problem Constrained Minimum Trace Factor Analysis (CMTFA), when the population covariance matrix $Σ_…
Finite Blocklength Analysis of Gaussian Random Coding in AWGN Channels under Covert Constraint
Xinchun Yu, Shuangqin Wei, Yuan Luo
This paper considers the achievability and converse bounds on the maximal channel coding rate at a given blocklength and error probability over AWGN channels. The problem stems fro…
Algebraic Properties of Wyner Common Information Solution under Graphical Constraints
Md Mahmudul Hasan, Shuangqing Wei, Ali Moharrer
The Constrained Minimum Determinant Factor Analysis (CMDFA) setting was motivated by Wyner's common information problem where we seek a latent representation of a given Gaussian ve…
