— Cooperative communications can help combat fading and hence can significantly increase the capacity of wireless networks. Although various schemes have been proposed to levera...
Network Coding (NC) can be efficiently combined with the "physical layer broadcast" property of wireless mediums to facilitate mutual exchange of independent information...
—A key technology in cooperative communications is distributed space-time coding (DSTC) which achieves spatial diversity gain from multiple relays. A novel DSTC, called randomize...
