移動通信多徑色散信道散射函數(shù)的分析與模擬
Analyzing and simulating the Scattering Function of Multipath Dispersion Chamrel in Urban Mobile Communications

摘要: 散射函數(shù)是描述時間-頻率色散信道特性的最重要的數(shù)學(xué)方法之一,它集中反映了信道在時域和頻域的色散特征,并還在一定程度上反映出角度色散的分布情況。本文對城市微蜂窩移動通信多徑色散信道的散射函數(shù)及其數(shù)學(xué)模型進(jìn)行了研究和推導(dǎo),并對不同色散影響情況下的移動信道散射函數(shù)模型進(jìn)行了仿真和分析。

Abstract: 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, the... -
