A novel satellite direct audio broadcasting (DAB) system based on code combining, packet combining (CCPC), and iterative decoding-so called the turbo coding principle, is presented. This new scheme provides not only the unprecedented coding gain from the turbo code and its iterative decoding, but also the gains induced by the code combining and the packet combining. We demonstrate the performance improvements, in terms of the bit error rate (BER) and word error rate (WER) for an AWGN channel and a Rayleigh fading channel with perfect channel state information (CSI) through simulations.
