Capacity-approaching turbo coding and iterative decoding for relay channels
IEEE Transactions on Communications(2005)
摘要
In this paper, we design turbo-based coding schemes for relay systems together with iterative decoding algorithms. In the proposed schemes, the source node sends coded information bits to both the relay and the destination nodes, while the relay simultaneously forwards its estimate for the previous coded block to the destination after decoding and re-encoding. The destination observes a superposit...
