Abstract
A communication device for a direct sequence code division multiple access (DS-CDMA) communication system is disclosed. The communication device comprises a CRC (Cyclic Redundancy Code) generator for generating CRC bits according to input data bits and adding the generated CRC bits to the input data bits; a channel encoder for encoding the CRC-added data bits using a coding rate R=1/6 convolutional code of a generator polynomial of (457, 755, 551, 637, 625, 727); and an interleaver for interleaving the coded data bits.
