抄録

This paper addresses a complexity reduction scheme for turbo decoding and demonstrates its impact on bit error rate performance in a wideband direct sequence code division multiple access (W-CDMA) mobile radio environment. The complexity reduction scheme combines concatenation of CRC with turbo coding and incorporates a CRC error-detection flag for terminating schemes of decoding iteration. The impact of the scheme on complexity reduction of turbo decoding is investigated using several coding parameters such as the maximum number of decoding iterations and interleaver length of the turbo codes. Miss-detechtion probability of CRC error-detection is also investigated in this paper.
