文章介绍了宽带短波(WBHF)信道研究的发展历程,根据ITS信道建模的方法,在对信道衰落特征及其噪声干扰统计特性进行分析的基础上建立了适当模型,并设定了特定环境下信道衰落模型及其噪声模型的相关参数。最后通过计算机仿真与实测数据加以比较,从散射函数能量分布、噪声时/频域电平以及噪声电平交叉率(LCR)方面验证了信道模型的合理性。
This paper introduces the development of broadband shortwave (WBHF) channel research. Based on the ITS channel modeling method, based on the analysis of the characteristics of channel fading and its statistical characteristics of noise interference, we set up an appropriate model and set the specific environment Channel fading model and its noise model related parameters. Finally, by comparing the computer simulation with the measured data, the rationality of the channel model is verified from the scattering function energy distribution, the noise / frequency domain level and the noise level cross rate (LCR).
