摘    要:在实际测量的基础上,通过对大量数据进行统计分析,应用数理统计方法对高速铁路弓网系统产生的无线电干扰场强进行研究,获得干扰电平的频率特性曲线.利用柯尔莫可洛夫一斯米洛夫检验判断干扰电平的概率分布,然后利用最大似然估计得到相应的参数,最后得出干扰的幅度概率分布.在此基础上,根据干扰源的特性得出了弓网系统的无线电干扰对通信系...

关 键 词:无线电干扰  频率特性  幅度概率分布  误码率  弓网系统

Abstract:Frequency characteristic of radio-frequency interference(RFI) produced by electrical multiple units pantograph and catenaries was obtained through mathematic statistic method,after the measured data were analyzed.The probability distribution of the interference level was judged using Kolmogorov-Smirnov test,and then the corresponding parameters of probability distribution of the interference level was estimated using maximum likelihood estimation,and then the amplitude probability distribution was obtained....
Keywords:radio-frequency interference(REI)  frequency characteristic  amplitude probability distribution  bit error ratio(BER)  electrical multiple units pantograph and catenaries
