Constructive Approaches to Perception-Aware Lossy Source Coding: Information-Theoretic Guidelines
Ali Hussein, Jun Chen, Chao Tian +1
Perception-aware lossy source coding has attracted significant recent interest. It augments the classical distortion criterion with an explicit perception constraint, thereby enabl…

On the Strong Converse Exponent and Error Exponent of the Classical Soft Covering
Xingyi He, S. Sandeep Pradhan, Andreas Winter
This paper establishes the exact strong converse exponent of the soft covering problem in the classical setting. This exponent characterizes the slowest achievable convergence spee…

Capacity-achieving Polar-based Codes with Sparsity Constraints on the Generator Matrices
James Chin-Jen Pang, Hessam Mahdavifar, S. Sandeep Pradhan
In this paper, we leverage polar codes and the well-established channel polarization to design capacity-achieving codes with a certain constraint on the weights of all the columns…
