Patent ID: 7810014

Claim:
An apparatus for stopping iterative decoding in a mobile communication system, comprising: a first constituent decoder for performing first constituent decoding of received signals and outputting a first constituent decoding result; a second constituent decoder for performing second constituent decoding of the received signals and outputting a second constituent decoding result; a first hard decision section for performing a first hard decision process for outputs of the first constituent decoder and outputting a first hard decision result; a second hard decision section for performing a second hard decision process for outputs of the second constituent decoder and outputting a second hard decision result; a first cyclic redundancy check (CRC) encoder for first CRC encoding outputs of the first hard decision section and outputting a first CRC encoding result; a second CRC encoder for second CRC encoding outputs of the second hard decision section and outputting a second CRC encoding result; and a stop condition determination section for checking a number of constituent decoding processes included in the first and the second CRC encoding results, and determining whether to stop iterative decoding according to whether the number of constituent decoding processes has reached a maximum number.
