超短波移动通信场强测试标准方法的研究

本文以专门的电波传播实测数据为基础,根据数理统计与电波传播理论,对移动通信场强测试应采用的测试区间长度、样本间隔、重复测量次数等问题进行了严格的误差分析.根据实测数据分析建立了信号衰落幅度概率分布的经验模型,并据此对国外专家的有关结论进行了修正.提出了在45个波长为长度的测试区间内,以一个波长的间隔均匀抽取样本,并重复测量4次的测试方法,作为对场强测试方法标准化的探讨.

Approach to Standard Method of Field Strength Measurement on VHF/UHF Mobile Radio

This paper gives detailed analysis about some important problems in mea- surement procedure of mobile radio signal,such as the length of measurement section,sample separation in space,and repeated measurement times.Based on data statistics,M distribution (when m=0.8) is developed as an experimental model of fast fading.It is necessary and sufficient to get 44 samples in the measurement sec- tion of 45 wavelengths.It is also necessary to repeat measurement 4 times in every section for obtaining the result of 90 percent confidence interval and less than 1dB error in estimate.
