WG 4: Construction of Network Codes and Grassmannian Codes
Chairs: Tuvi Etzion, Joachim Rosenthal
Work programme
Traditional coding theory is aware of two different construction issues, one of them a purely practical, where the other being more theoretical and particularly touching asymptotic aspects of coding. The former type of construction is interested in codes of small size and small length that come with efficient encoders and decoders and are ready for implementation in communication devices. The latter focuses on the existence of infinite families of codes for which information rate and error-correction capabilities are clearly bounded away from zero. Particularly in search of good network codes of relatively small size in small projective geometries intelligent searches based on assumptions on the inner symmetry of the code can significantly help the construction process. This task is of highly mathematical nature and requires strong computational power for the resulting searches. Judging the quality of its outcomes will require results from Working Group 1.
