30-300GHz毫米波（mmWave）频段目前正被追求以应对5G、WiFi和IoT网络不断增长的容量需求。由于频率较高，脉冲无线电(IR)在这个频段比现有的其他低频段更适合定位。除了精确定位外，超宽的带宽还可以在同一应用中同时使用多个中心频率，这为红外mmWave网络中的信息编码开辟了新的途径。本文提出了一种新的mmWave红外框架，它可以同时检测到达方向(DOA)和发射脉冲的中心频率。本文以新兴的石墨烯收发器为基础，在mmWave频段(100-300GHz)的较高频率范围内对所提出的框架进行了性能评估。数值实验表明，该框架能在20米处对0.1μWatt的mmWave脉冲进行1度精度的DOA检测，并能在10米处对3种不同的中心频率进行100%的分类。通过改变系统的脉冲率可以进一步提高这些性能。

英文摘要：
The 30-300GHz millimeter wave (mmWave) band is currently being pursued to combat the rising capacity demands in 5G, WiFi, and IoT networks. Due to the high frequency, impulse radio (IR) in this band is better suited for positioning than other existing low-frequency bands. Besides precision positioning, the exceptionally wide bandwidth also enables concurrent use of multiple center frequencies in the same application, which opens up additional avenues of information encoding in IR mmWave networks. In this paper, we propose a new mmWave IR framework that can simultaneously detect direction of arrival (DOA) as well as the center frequency of the transmitted pulse. Based on the emerging graphene-based transceivers, we evaluate the performance of the proposed framework in the higher frequency region of mmWave band (100-300GHz). Numerical experiments demonstrate that the proposed framework can detect the DOA of a 0.1 $\mu$Watt mmWave pulse within 1 degree of precision at 20 meters, and classify three different center frequencies with 100% accuracy from a distance of 10 meters. These performances could be further improved by trading off the pulse rate of the system.
