Ensemble-Tight Second-Order Asymptotics and Exponents for Guessing-Based Decoding with Abandonment
Vincent Y. F. Tan, Hamdi Joudeh
This paper considers guessing-based decoders with abandonment for discrete memoryless channels in which all codewords have the same composition. This class of decoders rank-orders…

Variable-Length Feedback Codes over Known and Unknown Channels with Non-vanishing Error Probabilities
Recep Can Yavas, Vincent Y. F. Tan
We study variable-length feedback (VLF) codes with noiseless feedback for discrete memoryless channels. We present a novel non-asymptotic bound, which analyzes the average error pr…

Distributed Detection with Empirically Observed Statistics
Haiyun He, Lin Zhou, Vincent Y. F. Tan
Consider a distributed detection problem in which the underlying distributions of the observations are unknown; instead of these distributions, noisy versions of empirically observ…
