Error detection and correction

Sequential decoding

Recognised by John Wozencraft, sequential decoding is a limited memory technique for decoding . Sequential decoding is mainly used as an approximate decoding algorithm for long constraint-length convolutional codes. This approach may not be as accurate as the Viterbi algorithm but can save a substantial amount of computer memory. It was used to decode a convolutional code in 1968 Pioneer 9 mission. Sequential decoding explores the tree code in such a way to try to minimise the computational cost and memory requirements to store the tree. There is a range of sequential decoding approaches based on the choice of metric and algorithm. Metrics include: * Fano metric * Zigangirov metric * Gallager metric Algorithms include: * Stack algorithm * Fano algorithm * Creeper algorithm (Wikipedia).

List-Decoding Multiplicity Codes - Swastik Kopparty

Swastik Kopparty Rutgers University April 10, 2012 We study the list-decodability of multiplicity codes. These codes, which are based on evaluations of high-degree polynomials and their derivatives, have rate approaching 1 while simultaneously allowing for sublinear-time error-correction.
