摘要:

本文提出了一种简单的参数多项式视线信道模型,适用于100-450 GHz频段。该频带包括两个流行的超第五代(B5 G)频段,即D频带(110-170 GHz)和低THz频带(约275-325 GHz)。本文的主要重点是推导出一个简单,紧凑,准确的分子吸收损耗模型为100-450 GHz频段。导出的模型依赖于简单的吸收线形状函数,该函数拟合到由复杂但精确的数据库方法给出的实际响应。该模型还可以简化100-450 GHz全范围内的特定子带,进一步简化吸收损耗估计。该模型被证明是非常准确的基准对精确的响应和类似的模型,由国际电信联盟无线电通信部门(ITU-R)。在高度潮湿的环境中,对于一公里的链路,损耗在$\pm$ 2 dB以内。因此,在通常被认为是较短距离的未来B5 G无线系统的情况下,其准确性甚至要好得多。

英文摘要:

This paper documents a simple parametric polynomial line-of-sight channel model for 100-450 GHz band. The band comprises two popular beyond fifth generation (B5G) frequency bands, namely, the D band (110-170 GHz) and the low-THz band (around 275-325 GHz). The main focus herein is to derive a simple, compact, and accurate molecular absorption loss model for the 100-450 GHz band. The derived model relies on simple absorption line shape functions that are fitted to the actual response given by complex but exact database approach. The model is also reducible for particular sub-bands within the full range of 100-450 GHz, further simplifying the absorption loss estimate. The proposed model is shown to be very accurate by benchmarking it against the exact response and the similar models given by International Telecommunication Union Radio Communication Sector (ITU-R). The loss is shown to be within $\pm$2 dBs from the exact response for one kilometer link in highly humid environment. Therefore, the its accuracy is even much better in the case of usually considered shorter range future B5G wireless systems.
