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 …

The Internet of Things refers to the aptitude of remotely connecting and monitoring anything,
anytime, and anywhere via futuristic wireless networks. Due to the unreliable wireless links …

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) …

Existing error correcting schemes approaching the capacity of orthogonal modulations are
mainly resorting to optimized bit-interleaved coded modulation (BICM) schemes with …

One advantage of incremental transmissions with feedback in point-to-point memoryless
channels is a reduction in average blocklength required to approach capacity. This paper …

We investigate PSK-LoRa modulation, which serves as an alternative to LoRa by
introducing additional information in the phase using Phase-Shift Keying (PSK) symbols …

Variable-length (VL) coding with feedback is a commonly used technique that can approach
point-to-point Shannon channel capacity with a significantly shorter average codeword …

In this paper, we present a low-density parity-check coded modulation approach addressing
orthogonal modulations with moderate order (between 8 and 32) over the additive white …

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 …
