论文摘要
长期演化（LTE）系统为移动通信提供了无处不在的覆盖范围，这使其成为有希望的候选人在环境反向散射通信中用作信号源。在本文中，我们提出了一个系统，在该系统中，反向散射设备通过更改其反射系数来调节环境LTE信号，并且接收器使用LTE电池特异性参考信号（CRS）来估计通道并从获得的通道脉冲脉冲响应估计中解调反向散射信号。我们首先概述整个系统，讨论接收器操作，然后提供有关拟议系统实用性的实验证据。
Long Term Evolution (LTE) systems provide ubiquitous coverage for mobile communications, which makes it a promising candidate to be used as a signal source in the ambient backscatter communications. In this paper, we propose a system in which a backscatter device modulates the ambient LTE signal by changing its reflection coefficient and the receiver uses the LTE Cell Specific Reference Signals (CRS) to estimate the channel and demodulates the backscattered signal from the obtained channel impulse response estimates. We first outline the overall system, discuss the receiver operation, and then provide experimental evidence on the practicality of the proposed system.
