摘要
多中继复用系统因其在通信传输性能和优化资源配置方面的潜力而成为深入研究的热点领域。大量的研究工作虽然提出了一些新的中继选择总体机制,仍缺乏新的针对多中继选择的配置算法。因此针对多中继选择和系统资源配置,提出了一个基于贝叶斯优化算法的多中继选择策略。该策略在信道容量和通信能耗两方面对协作通信传输进行优化。通过仿真表明,提出的多中继选择策略可以明显增加信道容量并延长系统生命周期,达到了提升通信性能和优化资源配置的目的。
For the capability to achieve higher resource utilization and better transmission performance, the multi-relay cooperative spatial multiplexing became a research focus with a tremendous development. However, most previous research only focused on the overall mechanism. As one multi-relay selection al- gorithm with the optimization of allocation of resources, a Multi-Relay Selection Strategy Based on Bayes- ian Optimization Algorithm was proposed, where higher channel capacity and resource utilization could be achieved. From the simulation, it was shown that the channel capacity was increased dramatically and the system lifetime was prolonged too. It is obviously that the transmission performance could be improved and the network resources allocation could be optimized by the proposed strategy.
