A combination of multiple turbo codes and multiple antennas with a reduced iterative decoder for DS-CDMA systems

In this paper a combined multiple turbo codes and multiple antenna diversity scheme for synchronous DS/CDMA systems over mobile radio fading channels is considered to improve the BER performance. In spite of the multiple structures, no time delay and less amount of computation can be achieved by a modified parallel mode decoding process and a reduced MAP algorithm using trellis code structure.
