A combined multiple turbo codes and multiple antenna diversity scheme for synchronous DS/CDMA systems over fading mobile radio channels is considered to improve the BER performance. In spite of the multiple structures no time delay and a lesser amount of computation can be achieved by a modified parallel mode decoding process and a reduced MAP algorithm using a code trellis structure. The performance of the proposed combining scheme is studied by means of simulation for a QPSK DS/CDMA system on a non-frequency selective Rayleigh fading channel.
