Demonstration of Time-Reversal in Indoor Ultra-Wideband Communication: Time Domain Measurement
摘要：
利用时域测量，我们评估了时间反转技术在超宽带（UWB）通信中的可行性。选择了一个典型的室内传播信道进行探索。接收和发射天线对之间的信道响应是使用时域设备测量的，该设备包括任意波发生器（AWG）和数字存储示波器（DSO）。信道响应的时间反演版本用AWG构造并在信道中重传。记录等效时间反转信道响应。测量了时间反转技术在视线（LOS）同极和交叉极场景中的特性。
英文摘要：
Using time domain measurements, we assess the feasibility of time-reversal technique in ultra-wideband (UWB) communication. A typical indoor propagation channel is selected for the exploration. The channel response between receive and transmit antenna pairs is measured using time domain equipments which include an arbitrary wave generator (AWG) and a digital storage oscilloscope (DSO). The time-reversed version of the channel response is constructed with AWG and re-transmitted in the channel. The equivalent time reversed channel response is recorded. The properties of the time reversal technique in the line of sight (LOS) co-polar and cross-polar scenarios are measured.
