Abstract

A coding scheme is specified which, compared to the prior art and with the system having a structure resolution of the same magnitude, allows an enlarged code size for the same number of code elements, and/or by which fewer code elements are required per code for a predetermined code size. The code elements are disposed with basic values in a matrix defined in a novel manner, with the matrix having a finer subdivision of the basic values than the subdivision corresponding to the structure resolution. Further development with mean-value formations are possible.
