论文摘要

由于FM覆盖范围在世界范围内无处不在,因此可以认为几种应用程序可以更好地利用该有用的频段。因此,研究和表征FM频段的通道特性对潜在的双向数字无线系统的兴趣很大。在本文中,我们介绍了在土耳其Kocaeli的Gebze进行的86 MHz现场测量结果。通过测量,确定了一些FM通道特性。对城市,丘陵地形和农村地区进行测量。我们的结果表明,FM频道预计有一个较大的覆盖面积,但与此同时,它具有较大的通道延迟。虽然大多数成本-207频道功率延迟概况模型也适用于FM频段,但对于城市环境和丘陵地形环境,频道簇和多余的延迟却高于COST-207型号的频道。由于5G系统的目的是利用较低的频段进行补充链接,因此FM频段可以被视为潜在频段之一,然后可以利用本研究中提出的通道模型进行性能分析。

As FM coverage is so ubiquitous around the world, several applications can be considered to better exploit this useful band. Thus, it is of significant interest to investigate and characterize channel properties of the FM Band for the potential two-way digital wireless systems. In this paper, we present the results of field measurements at 86 MHz conducted at Gebze, Kocaeli, Turkey. Through the measurements, some of the FM channel characteristics are identified. Measurements are performed for urban, hilly terrain, and rural areas. Our results show that the FM channel expectedly has a large coverage area but at the same time, it possesses large channel excess delays. While most of COST-207 channel power delay profile models are also applicable for the FM Band, for urban environments and hilly terrain environments, channel clusters and excess delays are higher than those of COST-207 models. As 5G systems aim to utilize lower frequency bands for supplementary links, FM Band can be considered as one of the potential bands and the channel models proposed in this study can then be exploited for performance analysis.
