Abstract
Feedback links are ubiquitous in modern communication systems. This dissertation is focused on the short-blocklength performance of coded communication systems with feedback and is organized in three main parts. The first section presents a novel reliability-output decoding algorithm for tail-biting convolutional codes, based on Raghavan and Baum's Reliability-Output Viterbi Algorithm (ROVA) for terminated convolutional codes. Whereas terminated convolutional codes suffer from a rate penalty at short blocklengths, tail-biting convolutional codes do not suffer from rate loss, making them throughput-efficient and suitable for used in reliability-based retransmission schemes with short blocklengths.
