A New Rateless Coded Cooperation Scheme for Multiple Access Channels
The conventional Rate-less 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, the authors develop a new RCC scheme using rate-less 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, they found that their scheme outperforms the conventional RCC scheme. Simulation results also validate the theoretical prediction.
