This paper proposes protograph-based Raptor-like (PBRL) codes as a class of rate-
compatible low-density parity-check codes for binary-input AWGN channels. As with the …

This paper presents a general approach for optimizing the number of symbols in increments
(packets of incremental redundancy) in a feedback communication system with a limited …

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) …

A status updating system is considered in which a variable length code is used to transmit
messages to a receiver over a noisy channel. The goal is to optimize the codewords lengths …

This paper focuses on the design and evaluation of pragmatic schemes for delay-sensitive
communication. Specifically, this contribution studies the operation of data links that employ …

Variable-length (VL) coding sends an initial codeword followed by subsequent
transmissions of incremental redundancy (IR) sent when the decoder indicates through …

One of the key challenges for future communication systems is to deal with fast changing
channels due to the mobility of users. Having a robust protocol capable of handling …

Wireless networks have been adjusting their transmit power, modulation order, and coding
rate based on the channel conditions for a long time. Such adaptive protocols aim to …

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 …

As sensing and instrumentation play an increasingly important role in systems controlled
over wired and wireless networks, the need to better understand delay-sensitive …
