Abstract
An improved distributed turbo coding (DTC) scheme, namely, systematic-bit-selection DTC, is proposed for a two-hop relay network implementing selective-relaying (SR). In the scheme, source broadcasts a punctured turbo code in order to increase the successful decoding rate of relay. The relay forwards systematic-bit to the destination in case of successful cyclic redundancy check (CRC). From the two versions of systematic-bit coming from relay and source respectively, the destination selects the one with higher signal-to-noise ratio (SNR) for turbo decoding. Simulation results show the improved bit error rate (BER) performance of our scheme.
