In wireless ad-hoc networks, network coding can take advantage of the bi-directional traffic flows to increase the achievable throughput. In this letter, on the one hand, cooperative diversity based on distributed cyclic delay diversity is integrated into the physical network coding scheme to combat fading in wireless channel. On the other hand, to reduce the system overhead for the coherent detection...
Exploiting the desirable properties of cyclic group coding, we develop a full-rate differential distributed space- frequency coding (DSFC) in the frequency domain for broadband non-regenerative wireless relaying systems. The pairwise error probability analysis demonstrates that our scheme guarantees a diversity order of Gd les min{ML1, ML2}, where M is the number of the relay nodes, and L1 and L2...
