Research on High-speed mobile radio Large-scale propagation characteristics and interference

Study of high speed radio wave characteristics is significant for development of High-speed mobile communication technology. According to the mobile radio propagation characteristics, a method of measurement of these characteristics is proposed in this paper. Based on the sophisticated measurement instruments and the virtual instrument technology, the high speed measurement system is established and conducted at one high-speed channel pilot section in China. Through the test and measured data, the propagation characteristic such as slow fading pass loss exponent and standard deviation of shadow fading, etc. is obtained. Furthermore, the influence of interference from pantograph-catenary disconnection discharge on high-speed mobile channel is analyzed.
