Claims
- 1. An encoding system characterized by:
- 1) block encoding means for encoding a block of input data bits to produce a codeword comprising plural code symbols in accordance with an error correction code;
- 2) means for producing a group of codewords of said code comprising said codeword and related codewords, respective ones of said related codewords differing from said codeword by a uniform change to respective sets of symbols of said codeword; and
- 3) means for arranging the code symbols of a selected codeword of said group, wherein the selected codeword corresponds to a maximal number of bit differences from previously arranged codewords in a preselected pattern.
- 2. The encoding system according to claim 1, wherein the error correction code comprises a Reed/Solomon code comprising a palindromic generator polynomial.
