论文摘要
小型细胞蜂窝基站将用于MMWave和Sub-THZ通信系统，以向移动用户提供多GBPS数据速率和可靠的覆盖范围。本文分析了Sub-THZ通信系统的基站覆盖范围以及通过蒙特卡洛模拟单细胞和多细胞案例的频谱效率的系统性能。这些模拟基于在纽约布鲁克林市中心进行的城市微区（UMI）环境中在142 GHz的室外野外测量中得出的现实渠道模型。单细胞基站可以提供一个半径为200 m的下行链路覆盖区域，7单元系统可以在142 GHz时提供一个半径为400 m的下行链路覆盖面积。使用1 GHz的下行链路带宽和100 MHz上行链路带宽，7细胞系统可提供约4.5 Gbps的下行链路平均数据速率和410 Mbps上行链路上行链路平均数据速率为142 GHz。
Small-cell cellular base stations are going to be used for mmWave and sub-THz communication systems to provide multi-Gbps data rates and reliable coverage to mobile users. This paper analyzes the base station coverage of sub-THz communication systems and the system performance in terms of spectral efficiency through Monte Carlo simulations for both single-cell and multi-cell cases. The simulations are based on realistic channel models derived from outdoor field measurements at 142 GHz in urban microcell (UMi) environments conducted in downtown Brooklyn, New York. The single-cell base station can provide a downlink coverage area with a radius of 200 m and the 7-cell system can provide a downlink coverage area with a radius of 400 m at 142 GHz. Using a 1 GHz downlink bandwidth and 100 MHz uplink bandwidth, the 7-cell system can provide about 4.5 Gbps downlink average data rate and 410 Mbps uplink average data rate at 142 GHz.
