Throughput analysis of multiple-access-relay channel based on rateless coding
In this paper, we consider a new scheme based on jointly network and rateless coding for a multiple-access relay channel. In the scheme, whenever the relay can decode multiple messages of the users, it jointly encodes them using a larger rateless code. This scheme is compared with direct transmission and the conventional relaying scheme in which the relay helps each user independently at orthogonal channels. The comparison is made by evaluating the throughput of different schemes. The analytical and the simulation results show that the proposed scheme outperforms the other ones at the cases considered.
