Title:
A METHOD AND DEVICE FOR INNER INTERLEAVE IN SERIAL CONCATENATED CONVOLUTIONAL CODE
Document Type and Number:
WIPO Patent Application WO/2003/096597
Kind Code:
A1
Abstract:
A method and device for inner interleave in Serial Concatenated convolutional Code (SCCC), include: inputted information bit sequence is coded, the coded output data is interleaved through puncturing and reconnecting, then the interleaved data is coded, the coded data is punctured and reconnected again in order to output concatenate output sequence&semi the method is characterized in that the said interleaving must satisfy the following condition: in concatenated code output sequence, parity bit for each information bit is equal&semi and condition of pseudo−random S interleaver is matched. Error correction performance of the invention is much better than those of packet interleaver, pseudo−random interleaver, pseudo−random S interleaver. The effect is especially remarkable in long data at low error rate.
