Abstract

A prospective frequency band for short range communication is around 300 GHz where sufficient bandwidth is available for high data rates. Up- and down converters providing around 20 GHz bandwidth at a carrier frequency within 260 GHz to 400 GHz have been used. At such high frequencies, the propagation properties differ significantly from the known behavior at lower frequencies. Hence, different scenarios have been investigated: direct line-of-sight transmission, multiple reflections at dielectric surfaces and reflection on compound materials such as computer boards (PCBs). Data rates up to 42 Gbit/s have been shown. Additionally, an advanced modulation format (PAM-4) has been tested.
300 GHz高速传输的传播方案研究
近距离通信的预期频带约为300千兆赫,其中有足够的带宽可用于高数据速率。已经使用了在260 GHz到400 GHz的载波频率上提供大约20 GHz带宽的上下转换器。在如此高的频率下,传播特性与已知的较低频率下的行为显著不同。因此,研究人员研究了不同的场景:直接视线传输、介质表面的多次反射和复合材料(如计算机板(pcb))上的反射。数据传输速率可达42gbit /s。此外,还测试了一种高级调制格式(PAM-4)。
