摘要：An encoder for a wideband CDMA communications system comprises an outer

Reed-Solomon code encoder and an inner parallel concatenated convolutional code(PCCC) or turbo code encoder. An iterative PCCC decoder, for decoding the inner code,includes summing functions in forward and feedback paths for producing extrinsicinformation to enhance soft decoding decisions by first and second decoders insuccessive decoding iterations. An outer code decoder connected following the PCCCdecoder also can provide serial feedback information for enhancing iterative decisions bythe PCCC decoder.
