On The Effectiveness of Cooperation Diversity and Truncated ARQ in Single Relay Wireless Networks: A Cross-Layer Study
协同分集和截断ARQ在单中继无线网的使用：一种交互层研究

In this paper,a cross-layer cooperative design is developed under the constraint of maximum transmission number per node in an uncoded two-hop relay network. Two-type simple single-relay adaptive cooperative protocols are proposed in order to exploit a combined spatial and time diversity. Analysis and simulation show that for the asymmetric multi-hop relay wireless networks,the cooperative protocols enable effective antenna/energy share and remarkable frame error rateperformance gain in block fading channels at the moderate loss of average throughput due to truncated ARQ(Automatic Repeat Request) re-transmissions.
