Abstract :
The conventional rateless coded cooperation (RCC) operates in full-duplex and non-orthogonal multiples access channel (MAC) aiming to enlarge outage capacity with multiplexed Raptor code of high complexity. In this paper, we develop a new RCC scheme using rateless code, which operates in the practical half-duplex or orthogonal channel aiming to achieves coding gain in high SNR region with only one raptor code. By deriving the outage probability, we found that our scheme outperforms the conventional RCC scheme. Simulation results also validate the theoretical prediction.
