This monograph presents a unified treatment of single-and multi-user problems in
Shannon's information theory where we depart from the requirement that the error …

This paper presents a variable-length decision-feedback coding scheme that achieves high
rates at short blocklengths. This scheme uses the reliability-output Viterbi algorithm (ROVA) …

We present extensions to Raghavan and Baum's reliability-output Viterbi algorithm (ROVA)
to accommodate tail-biting convolutional codes. These tail-biting reliability-output algorithms …

This paper investigates basic trade-offs between energy and delay in wireless
communication systems using finite blocklength theory. We first assume that data arrive in …

We consider a two-user discrete memoryless multiple access channel with a common stop-
feedback signal from the receiver to both transmitters. The achievable regions are …

This paper reviews recent results from the UCLA Communication Systems Laboratory on the
use of incremental redundancy. For channels with ACK/NACK feedback, this paper reviews …

In an effort to account for the latency cost of error detection at short blocklengths, we
simulate a two-phase feedback-based incremental redundancy scheme. This scheme …

Feedback links are ubiquitous in modern communication systems. This dissertation is
focused on the short-blocklength performance of coded communication systems with …

We derive the optimum second-order coding rates, known as second-order capacities, for
erasure and list decoding. For erasure decoding for discrete memoryless channels, we show …

This paper studies variable-length coding with noise-less feedback for discrete memoryless
channels. Yamamoto and Itoh's two-phase scheme achieves the optimal error-exponent, but …
