Abstract :
In this paper, a practical distributed turbo code (DTC) and its corresponding decoding scheme at destination are presented. The transmission is divided into two phases. In the first phase, the source broadcasts a turbo code to both relay and destination. In the second phase, the relay forwards the decoded systematic bits to the destination in case of no CRC errors. Further, a modified turbo decoder is designed at destination to ensure that the destination makes full use of the received bits whether from source or relay. Simulation results demonstrate a marked BER performance without an increase of computation complexity.
