论文摘要
本文记录了100-450 GHz频段的简单参数多项式通道模型。该乐队包括两个流行的第五代（B5G）频带，即D乐队（110-170 GHz）和低THZ频段（约275-325 GHz）。这里的主要重点是为100-450 GHz带推导一个简单，紧凑，准确的分子吸收损失模型。派生的模型依赖于简单的吸收线形状函数，这些函数适合通过复杂但精确的数据库方法给出的实际响应。该模型还可以降低100-450 GHz的整个范围内的特定子频段，从而进一步简化了吸收损失估计值。通过对确切响应和国际电信联盟无线电通信行业（ITU-R）进行基准基准测试，提出的模型被证明是非常准确的。在高度潮湿的环境中，从一个公里的链接中的确切响应中，损失显示在$ \ pm $ 2 dbs之内。因此，在通常被认为较短的范围未来的B5G无线系统的情况下，其准确性甚至更好。
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.
