| 摘 要： | 为分析城镇厂区的MIMO信道特性,文中建立了特定厂区的3D确定性模型,并针对2.45 GHz和5.8 GHz两种载波频率,利用Wireless Insite软件对厂区MIMO信道的接收功率、路径损耗和时延扩展等信道特性参数进行了仿真分析。结果表明,4×4MIMO系统下两种载波频率路径损耗相差不大,2.45 GHz相对5.8 GHz能获得较高的接收功率,但时延扩展严重。综合考虑,5.8 GHz频段更适合城镇厂区MIMO信道的铺设,但需要考虑增加发射功率和减小覆盖范围等问题。

| Abstract: | In order to analyze factory MIMO channel characteristics in cites and towns, a 3D deterministic model of the specific factory is established, and aming at two carrier frequencyies 2.45GHz and 5.8GHz, factory MIMO channel parameters, such as received power, path loss, delay spread and so on, are simulated and analyzed with the software platform of Wireless Insite. Simulation results show that the path losses of both carriers in 4×4MIMO system almost have no difference, and 2.45GHz can obtain fairly high received power relatively to 5.8GHz, but with serious delay-spread. From overall consideration, 5.8GHz is more suitable for designing a factory MIMO channel, but needs to increase the transmission power and reduce the coverage area. |
