Recently, turbo codes have received great attention due to their outstanding performance. In the thesis, we evaluate the performance of turbo codes in direct sequence spread spectrum multiple access (DS/SSMA) systems, and propose two different packet-combining methods. The combining methods use the information in the previously received packets to increase the probability of correct decoding for the latest packet. Simulation results indicate that turbo codes have better throughput performance than convolutional codes in DS/SSMA systems and the proposed packet-combining methods improve the performance of turbo coded DS/SSMA systems.
