Fault-Tolerant Dot-Product Engines
Coding schemes are presented that provide the ability to correct and detect
computational errors while using dot-product engines for integer vector--matrix
multiplication. Both the -metric and the Hamming metric are considered
Prefixless q-ary balanced codes with fast syndrome-based error correction
Abstract: We investigate a Knuth-like scheme for balancing q-ary codewords, which has the virtue that look-up tables for coding and decoding the prefix are avoided by using precoding and error correction techniques. We show how the scheme can be extended to allow for error correction of single channel errors using a fast decoding algorithm that depends on syndromes only, making it considerably faster compared to the prior art exhaustive decoding strategy. A comparison between the new and prior art schemes, both in terms of redundancy and error performance, completes the study

Introduction to Forward-Error-Correcting Coding
This reference publication introduces forward error correcting (FEC) and stresses definitions and basic calculations for use by engineers. The seven chapters include 41 example problems, worked in detail to illustrate points. A glossary of terms is included, as well as an appendix on the Q function. Block and convolutional codes are covered
