摘要:

提出了一种非平稳车辆到车辆(V2 V)多输入多输出(MIMO)信道的实用模型。新模型考虑了多普勒频率输出相位的精确性,并通过泰勒级数展开进行简化。它也适用于生成具有移动发射机(MT)和移动接收机(MR)的任意速度和轨迹的V2 V信道系数。同时,对路径时延和功率等信道参数进行了研究和分析。统计特性的封闭式表达式,即,在到达角和离开角服从Von Mises(VM)分布的情况下,推导了时间自相关函数(TACF)和空间互相关函数(SCCF)。此外,理论、仿真和实测结果之间的良好一致性验证了该模型的正确性和实用性。

英文摘要:

In this paper, a practical model for non-stationary Vehicle-to-Vehicle (V2V) multiple-input multiple-output (MIMO) channels is proposed. The new model considers more accurate output phase of Doppler frequency and is simplified by the Taylor series expansions. It is also suitable for generating the V2V channel coefficient with arbitrary velocities and trajectories of the mobile transmitter (MT) and mobile receiver (MR). Meanwhile, the channel parameters of path delay and power are investigated and analyzed. The closed-form expressions of statistical properties, i.e., temporal autocorrelation function (TACF) and spatial cross-correlation function (SCCF) are also derived with the angle of arrival (AoA) and angle of departure (AoD) obeying the Von Mises (VM) distribution. In addition, the good agreements between the theoretical, simulated and measured results validate the correctness and usefulness of the proposed model.
