Title: Error correction method using turbo code
Inventor: KIM DONG HWAN
IPC: H04B7/005
Filed: 2002-10-28
Abstract: PURPOSE: An error correcting method using a turbo code is provided to reduce the number of re-transmission by re-transmitting systematic bits when data is re-transmitted because of an error. CONSTITUTION: When only a portion of encoded bit stream is transmitted at a code rate of 2/3 by using a turbo encoder having a code rate of 1/3, a receiving end decodes it, and if there is no error through a CRC(Cyclic Redundancy Check), an ACK signal is transmitted to a sending end. If an error occurs during decoding of an initial code rate of 2/3, systematic bits are added to some of remaining parity bits, which were not transmitted for the initial transmission, and re-transmitted, on which a decoding is performed at a code rate of 1/2. If an error occurs also in this process, re-transmission is requested, remaining parity bits are received, combined with a bit stream which has been previously received and stored, on which a decoding is performed at a code rate of 1/3. Thereafter, if there is no error through the CRC, an ACK signal is transmitted to the sending end.
