研究了一种双节点全双工通信系统，其中假设两个节点都具有能量收集能力(EH)。在所提出的模型中，节点B获取由节点A耗散的射频能量，节点A同时将其信号发送回节点A。此外，通过利用节点B的关键信息，包括其信道状态信息和电池使用情况，采用两种EH方式，提出了一种最小传输协议。在节点B具有足够高的剩余能量以保证节点A成功译码的前提下，允许节点B始终进行传输。此外，利用马尔可夫链模型可以建立同时具有EH和信号传输能力的协议，由此我们可以得到节点A的平稳分布和中断概率。
A bi-node full-duplex communications system, in which both nodes are assumed to have the capability of energy harvesting (EH), is investigated. In the proposed model, node B harvests radio frequency energy that dissipated by node A, to which the former will transmit its signal back simultaneously. Furthermore, by exploiting node B’s critical information, including its channel state information and the usage of its battery, a minimum transmission protocol is proposed by employing two kinds of EH-manners. Note that node B is allowed to always transmit, provided that its residual energy is high enough to ensure a successful decoding at node A. In addition, the proposed protocol with capabilities of both EH and signal transmission can be developed by employing a Markov-chain model, following which we can derive both the stationary distribution and the outage probability of node A. Finally, numerical results validate the proposed theoretical analysis.
