Apparatus and method for stopping iterative decoding in a cdma mobile communications system

When the present invention is a CDMA mobile communication relates to an iterative decoding stop device and a method using a turbo code in the system, in particular not using a CRC for error detection to a frame input to the turbo encoder does or can not be used, instead, to provide a new stopping criterion that reduces unnecessary iterations can stop the turbo decoding. Also discloses an error detection code and an apparatus and method for combined application of the new turbo decoding stopping criterion in order, even if used by a CRC for error detection to a frame input to the turbo encoder shorten the decoding time and reduce power consumption of a decoder.
