Frank Kschischang is an outstanding research engineer and educator whose highly influential work on error-correcting codes significantly shaped the development of algebraic coding theory and iterative decoding methods. His theoretical contributions on the sum-product algorithm laid the foundation of the modern theory of codes on graphs. His work on network coding and fibre optic channel revealed the fundamental limits of information transmission in communication networks and significantly advanced the state-of-art in the theory and practice of digital communications. Frank Kschischang has been extremely active in leadership positions in several well-established engineering societies and conferences.
