摘要

本文在瑞利衰落模型下

研究了高频电离层信道中多径时延与多普勒频移的随机特性.导出了它们的概率分布

并讨论了瞬时多径时延和瞬时多普勒频移与平均归一化功率之间的关系.

Abstract

In this paper

with Rayleigh fading the random characteristics of multipath time delay and Doppler shift in HF ionospheric channels is discussed. It’ s distribution densities are theoretically derived. An interrelation between the instantaneous multipath time delay （or Doppler shift） and the average normalized power is revealed.
