论文摘要
在这封信中，提出了一种新颖的无线驱动协议，以最大程度地提高基于能量收集（EH）的认知无线网络的系统吞吐量，同时满足最低主要用户率要求。对于EH，我们利用专用的无线电源从主要基站的无线电源传输以及由于初级和二级用户之间的无线信息传输而可用的环境电源传输。具体而言，我们证明了优化问题的凸度，并获得了半锁定形式的全球最佳解决方案。数值结果验证了分析，并显示了针对各种系统参数的基准方案的平均绩效提高$ 70 \％$。
In this letter, a novel wireless powered protocol is proposed to maximize the system throughput of an energy harvesting (EH) based cognitive radio network, while satisfying a minimum primary user rate requirement. For EH, we exploit both dedicated wireless power transfer from primary base station as well as ambient ones available due to wireless information transfer among primary and secondary users. Specifically, we prove convexity of the optimization problem and obtain semi-closed-form for globally optimal solution. Numerical results validate the analysis, and show an average performance improvement of $70\%$ over benchmark scheme for various system parameters.
