论文摘要
在本文中，研究了无线传感器继电器网络（WSRN）的速率能量区域，并在干扰器存在下进行能量收获。在该模型中，源通信到配备了单个天线的目的地，并通过在波束成形下的多个Antenna合作继电器进行能量收集约束。同时，有一个干扰器打算打扰沟通。继电器以半双链模式起作用，并且知道所有通道状态信息（CSI）。当继电器在接力赛处采用波束形成时，可以将网络建模为等效的高斯任意变化通道（GAVC）。我们表征可实现的速率能量区域。由于该问题是非凸，因此我们提出了三种将其转换为半准编程问题（SDP）的方法，并获得了速率能量区域的两个特殊边界点的闭合形式表达。最后，模拟显示了拟议方案的速率能量区域和抗界面性能。
In this paper, the rate-energy region is studied for the wireless sensor relay network (WSRN) with energy harvesting in the presence of a jammer. In the model, a source communicates to a destination equipped with a single antenna with energy harvesting constraint through a multi-antenna cooperative relay under beamforming. Meanwhile, there is a jammer intended to disturb the communication. The relay works in half-duplex mode and knows all the channel state information (CSI). When beamforming is employed at the relay, the network can be modeled as an equivalent Gaussian arbitrarily varying channel (GAVC). We characterize the achievable rate-energy region. Since the problem is non-convex, we present three methods to transform it into a semi-definite programming problem (SDP), and the closed-form expression for two special boundary points of the rate-energy region is obtained. Finally, the simulations show the rate-energy region and the anti-jamming performance of the proposed scheme.
