Abstract
Small scale characteristics are very important for the vehicle-to-vehicle (V2V) radio channel. In this paper, the Akaike information criterion (AIC), which aims to solve the problem of the optimal model selection, is used to select the best fading distribution for vehicle radio channel from Rayleigh and Rician distributions in a highway environment. The measurement results show that the Rician distribution has the best fitting for the V2V radio channel in a highway communication environment. Influence from surroundings on the small scale characteristics are analyzed. The Rician K-factors are extracted and modeled based on the measurement data. It can be found that the mean value of Rician K-factor is around 4.86 dB in this scenario.
对于车对车(V2V)无线信道来说,小规模特性非常重要。本文采用赤池信息准则(Akaike information criterion, AIC)来解决公路环境下车辆无线电信道的最优模型选择问题,从瑞利分布和瑞利分布中选择最优衰落分布。测量结果表明,在高速公路通信环境下,该分布最适合V2V无线信道。分析了环境对小尺度特性的影响。根据实测数据,提取出相应的系数,并建立模型。可以发现,在这种情况下,专家k因子的平均值在4.86 dB左右。
