Interleaving process coding/decoding mechanism with symbol sequence written line/line separating positions and forming intra column permutations and preserving divisibility/obtaining interleaved sequences.

摘要

The symbol sequence interleaving method has a symbol sequence in an interleaved sequence. The sequence of symbols are written line by line to separate different positions (501). The symbols are permutated to columns with intra column permutations (502). A third step preserving divisibility of a polynomial reading the permutation to obtain the interleaved sequence (506) is then carried out.
