摘要
散射函数是描述时间-频率色散信道特性的最重要的数学方法之一,它集中反映了信道在时域和频域的色散特征,并还在一定程度上反映出角度色散的分布情况。本文对城市微蜂窝移动通信多径色散信道的散射函数及其数学模型进行了研究和推导,并对不同色散影响情况下的移动信道散射函数模型进行了仿真和分析。
The scattering function is one of most important mathematical method describing time-frequency dispersion channel performance, which embodies a concentrated reflection of the dispersion characteristics of the mobile radio channel in time and frequency domain, and reflects the angle dispersion distributed performance of the channel to a certain extent. The paper researches the scatter function as well as its mathematical models of multipath dispersion channel in urban microcellular mobile Communications, then simulates and analyzes the scattering function modei of mobile channels with different dispersions.
