Abstract
针对协作通信网的中继选择问题,提出了一种基于贝叶斯推理的自适应中继选择方案.该方案拓展地运用了放大转发协议的原理,准确地分析了中继节点后验概率,并以此选取最优的中继节点进行信息传输.实验仿真结果表明,该方案在信噪比恒定的情况下,显著地提高了网络性能.
Aiming at the relay selection problem in collaborative communication networks,a Bayesian inference-based relay selection scheme is proposed.The scheme extends the principle of amplify-and-forward protocol,and accurately calculates the poste-rior probability of the relay node.Then the optimal relay node for information transmission is selected.The simulation results show that the proposed scheme significantly improves the network performance in the case of constant signal-to-noise ratio.
