Abstract: PROBLEM TO BE SOLVED: To reduce required memory capacity and to reduce costs by simplifying a turbo decoder of a receiver in a TDD/CDMA communication system using turbo codes. SOLUTION: An interactive turbo demodulator and a demodulation method for a communication signal data with an error correction function are provided. The decoder implements a stopping rule through use of signature codes to determine whether successive iterations of decoder data are the same. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: An iterative turbo decoder for a receiving unit of a wireless communication system and method for error correcting received communication signal data are provided. The decoder implements a stopping rule through use of signature codes to determine whether successive iterations of decoder data are the same. Memory requirements are reduced by calculation of a compressed signature of decoder estimate data.
