摘要
本文依据在北京市区所作移动通信场强测试资料,分析了频率为450MHz 和900MHz、平坦地形条件下的市区移动通信场强特性,给出了快衰落的统计分布和穿过率、慢衰落统计分布以及场强中值随距离的变化曲线。
Based on the mobile radio field strength data measured in the urban of Beijing, A study on the characterios of mobile field strength in the urban where terrain is flat has been made.The distribution of fast fade,Level-crossing rate,statisticses of slow fade,and the curves of the media of field strength versus propagation distance have been given in this paper.
