由反射器引起的多径引起的RF信道中的时间色散。以及传播环境中的散射体，在设计高速率数字无线电系统和无线调制解调器时必须加以考虑。本文介绍了用于从测量数据中表征RF信道中的时间色散和路径损耗的参数。在讨论的时间分散参数，分析和测量数据的结果，在一个大的火车站在902 - 928 MHz IBM波段。
Time dispersion in RF dhannels, induced by multipath caused by reflectors. and scatterers in the propagation environment, must be considered when designing high-rate digital radio systems and wireless modems. This article describes the parameters used to characterize time dispersion and path loss in an RF channel from measured data. Following a discussion of the time dispersion parameters, the analysis and results of measurement data taken in a large train yard in the 902 928 MHz IBM band are presented.
