传播模型 meaning in English
dynamic transmission model
propagation model
Examples
- The special radar signal environment is very complex in electronic warfare , so the received signals always have low signal noise ratio ( snr ) and complex model . under this kind of environment , the estimation precision of time delay and the capability of restraining noise fallen down in the conventional methods
现在常用的几种时延估计方法,只适用于信号为平稳信号,噪声为加性高斯白噪声这样比较简单的情况。像雷达信号这样复杂的传播模型,这些常用的时延估计方法就不适用了。 - Accordingly ray tracing model for microcells propagation prediction has become an important subject . this paper discussed the characteristic of propagation in symmetrical atmosphere on the earth , and introduced several kinds of traditional path loss propagation model in land mobile communication system , also pointed out the localization of these models based on experiential methods
本文首先讨论了在地球表面均匀大气中的无线电波传播的基本特性,介绍了陆地移动通信系统中常用的几种电波传播路径损耗经验性预测模型,并指出了这些经验性传播模型对于微蜂窝小区无线电波传播特性研究的局限性。
