多径色散与平衰落之相关特性

Correlationship Between Multipath Dispersion and Flat Fading

本文依据实验和计算机随机模拟结果，分析了多径传播引起的平衰落深度与带内线性幅度色散（频率选择性衰落）等概率值之间的相关性，表明了两者之间存在极好的统计线性关系，这为用平衰落预测频率选择性衰落提供了新的有效途径，平衰落的预测是成熟的。

Based on data measured in China and Japan and computer simulation results,the correlationship is analyzed between equi probability values of the in band linear amplitude dispersion (frequency-selecting fading)and flat fading depth due to multipath propagation,and it is shown that there statistically exists an excellent linear relationship between them,which provides a simple and valuable method for predicting the selecting fading by means of the flat fading depth.
