本文研究了短波电离层反射衰落信道的时频选择特性。电离层和对流层的确定性和随机的空间和时间变化都包括在确定信号从多层电离层反射的信道的多径延迟和多普勒频率扩展中。给出了一个典型传播条件下多径谱和多普勒谱的扩散性的例子。
The time and frequency selective behavior of a fading HF ionospheric reflection channel is considered in this paper. Both deterministic and random spatial and temporal variations of the ionosphere and the troposphere are included in determining the multipath delay and Doppler frequency spreading of a channel in which the signals are reflected off of a multilayered ionosphere. An example which illustrates the diffuseness of the multipath and Doppler spectra under typical propagation conditions is given.
