Abstract

In this work, for a turbo trellis coded communication system over relay channel, system performance is tried to be enhanced by employing different mappings at relay and source. Moreover, considering the trellis encoders at the source and relay together, the trellis of relay encoder is designed to minimize the overall system symbol error rate. The performance of the proposed algoritms are figured out via simulations and superior performance is achieved compared with classical channel coded scheme.
