Abstract
An interleaver provision method for providing a continuous length, an interleaving method, and a turbo-encoder thereof are disclosed. The interleaving method selects a basic interleaver having a proper length from among the basic interleaver set, which is predetermined to have the length represented by a multiple of the ARP fluctuation vector period. The interleaving method performs the dummy insertion and the pruning process to have the length acting as the basic-interleaver length, so that it can provide the ARP interleaver having a continuous length.
Claims5
An interleaving method comprising:
- inserting dummy information in an original sequence by a predetermined length corresponding to a difference in length between a basic interleaver selected from among a basic interleaver set and the original sequence;
- interleaving the sequence in which the dummy information is inserted using the basic interleaver, the sequence having the length of the basic interleaver;
- removing indexes corresponding to the dummy information from indexes of the interleaved sequence;
- and
- outputting the interleaved sequence from which the dummy information is removed,
- wherein the basic interleaver has a length represented by a multiple of a specific length,
- wherein the dummy information in the inserting the dummy information is inserted in an arbitrarily-selected position between the original sequences, and
- wherein the arbitrarily-selected position in which the dummy information is inserted includes an initial position of the original sequence.
