Algebra and Error Correcting Codes

Lecturers & Examiners: Prof. Dr. Hans-Andrea Loeliger

VVZ CR 4.2

Last Updated: 2026-02-05 16:37:31

Abstract

The course is an introduction to error correcting codes covering both classical algebraic codes and modern iterative decoding. The course includes a self-contained introduction of the pertinent basics of "abstract" algebra.

Objective

Content

Error correcting codes: coding and modulation, linear codes, Hamming space codes, Euclidean space codes, trellises and Viterbi decoding, convolutional codes, factor graphs and message passing algorithms, low-density parity check codes, turbo codes, polar codes, Reed-Solomon codes. Algebra: groups, rings, homomorphisms, quotient groups, ideals, finite fields, vector spaces, polynomials.
