Abstract
A new algorithm of the block encoding that can be implemented in such a way that block of several letters is coded using almost the same number of operations as a usual code uses for one letter is suggested. The new algorithm is based on methods of grouping of alphabet letters suggested recently in B. Ryabko, J. Astola (2003), B. Ryabko, J. Rissanen (2003) which combines letters from a large alphabet into a small number of subsets without an essential increase of the code redundancy.
