基于雨衰雪衰影响的空间信道统计模型
A Geometrical Statistical Channel Model Based on Rain and Snow Fading Effect
摘要
Abstract
For the complexity of channel parameters estimation for angle of arrival( AOA) and time of arrival (TOA) in some special mobile communication environment,an outdoor statistical channel model based on the uniform distribution of the scatterers is proposed. In this model,the canopy of tree is distributed evenly in the oval area around the mobile station and the base station. The influence of rainfall and snowfall on the sig-nal transmission is analyzed by the relative permittivity of canopy layer in wet environment. Closed-form ex-pressions for marginal and joint probability density function(PDF) of AOA,TOA in the outdoor macrocell wireless environment are derived. The TOA and the AOA of the signal increases with the increasing of the a-mount of rainfall and snowfall. In additional,the signal will be blocked when the the relative permittivity is e-qual to 4. 5. Channel parameter estimation results of the model show that the analysis is correct and applica-ble to macrocell environment,which promotes the research on mobile communication channel model.关键词
