本文针对移动到移动(M2M)通信环境，提出了一种三维几何信道模型。该模型将已有的M2M和固定到移动(F2M)通信信道的2-D和3-D几何信道模型合并为一个广义模型。利用该模型，推导了到达角和到达时间在方位和仰角平面上的联合概率密度函数的闭合表达式。这些结果随后被模拟和可用的现场测量所验证。并与已有的2-D和3-D信道模型进行了综合比较，结果表明，在M2M和F2M通信环境中，通过调整相应的信道参数，许多值得注意的几何信道模型成为本文所提出的广义3-D几何信道模型的特例。因此，所提出的三维信道模型可以作为移动自组织网络、车载自组织网络和智能交通系统建模的有用工具。
In this paper, we develop a 3-D geometrical channel model for mobile-to-mobile (M2M) communication environment. The proposed model combines most of the existing 2-D and 3-D geometrical channel models for M2M and fixed-to-mobile (F2M) communication channels into one generalized model. Using the proposed model, closed-form expressions for the joint probability density function of angle-of-arrival and time-of-arrival in azimuth and elevation planes are derived. These results are then verified by simulations and available field measurements. Furthermore, comprehensive comparisons of the proposed channel model are carried out with the existing 2-D and 3-D channel models in the literature, which show that many notable geometrical channel models in M2M and F2M communication environments become the special cases of our proposed generalized 3-D geometrical channel model by adjusting corresponding channel parameters. Consequently, the proposed 3-D channel model can be taken as a useful tool for modeling mobile ad hoc networks , vehicular ad hoc networks, and intelligent transportation systems.
