In order to avoid the loss of spectral efficiency (throughput) caused by half-duplex mode and further improve achievable throughput performance of wireless multi-hop network, a relaying technique that utilizes two sets of relays and physical network coding over bi-directional traffic flows is introduced. We term such technique as Bi-directional Successive Relaying based on Physical Network Coding...
In multi-hop wireless networks, network coding can take advantage of the bi-directional traffic flows to increase the achievable throughput. To combat fading in wireless channel, cooperative diversity is integrated into the network-coding schemes. In this paper, we propose an opportunistic cooperative network-coding scheme based on space-time coding (OCNC), which combats channel fading and improves...
