Distributed Turbo Coding With Hybrid Relaying Protocols

Distributed Turbo Coding (DTC) has been shown to be an effective coding scheme to approach the capacity of a wireless relay network. However, most of existing DTC schemes only consider a relay network with single relay node and assume that relay can perform an error free decoding, which the authors refer to as a perfect DTC scheme. In this paper, the authors consider a general 2- hop relay network with an arbitrary number of relays and design the DTC for such a network when taking into account imperfect decoding at each relay.
