N2 - In this contribution, we present a low-complexity differential cooperation scheme for communications over two-way relay channels. More specifically, a frame of Differential Phase- Shift Keying (DPSK) symbols is generated at the source nodes, while differential distributed space-time block coding (DDSTBC) scheme is invoked at each cooperating relay node. Since non-coherent detection can be carried out to recover the transmitted signals at both relay and destination nodes, it is not necessary to incorporate any channel estimation components in our proposed system. A selection relaying protocol based on CRC is utilized at the relay nodes to counteract the negative effects of error propagation. It is shown that full diversity order is still attainable at the destination nodes, even when the source-to-relay link is not protected by powerful channel codes with high computational complexity.
