AI中文摘要：
磁感应（MI）通信可应用于矿井和地下河流等一些地对地下场景。为提高MI通信的传输速率，我们提出一种具有放大转发（AF）中继的协作MI（CMI）方案。与现有研究不同，我们主要关注具有任意天线位置和方向（天线部署，AD）的中继。我们推导了中继的CMI可达数据速率增益（CMG）的闭式表达式以及CMI信道带宽的闭式表达式。仿真表明，具有适当AD的中继可以显著提高MI系统的可达速率。
英文摘要：
Magnetic Induction (MI) communication can be applied in some through-the-earth scenarios such as mines and underground rivers. To increase the transmission rate of MI communications, we propose a cooperative MI (CMI) scheme with an amplify-and-forward (AF) relay. Different from existing studies, we mainly focus on the relay with arbitrary antenna position and orientation (antenna deployment, AD). We derive the closed-form expression of CMI achievable data rate gain (CMG) for the relay and the closed-form expression of CMI channel bandwidth. Simulations reveal that a relay with appropriate AD could yield a significant increase in the achievable rate for MI systems.
