无线信道的处理是决定移动的通信系统工作能力的一个重要方面。由于信道行为受环境影响，这导致在不同环境中的不同行为，因此天线设计（合成）也变得依赖于环境（时变）。本文基于采样天线的思想，提出了一种时变信道下汽车天线系统容量最大化的设计方法。考虑了真实的世界的约束条件，如可用空间、发射功率、天线的数量和布置。除了理论，不同的例子优化单输入单输出（SISO）和2×2多输入多输出（MIMO）系统的车对车（C2C）通信将提出和比较。总共考虑并比较了车辆上多达16个可能的天线位置。三维射线跟踪工具计算用于这种合成方法的通信信道。结果表明，定向天线元件，在±驾驶方向的重点，可以用来增加容量，特别是在安全关键的C2C场景。
The handling of the radio channel is an important aspect that determines the working capability of a mobile communication system. Since the channel behavior is influenced by the environment, which leads to a different behavior in different environments, the antenna design (synthesis) becomes environment dependent (time-variant) as well. In this paper, a capacity maximizing approach to design automotive antenna systems for time-variant channels based on the approach of sampling antennas is presented. Real world constraints such as the available space, transmit power, the number and arrangement of the antennas are taken into account. Besides the theory, different examples for optimizing Single-Input-Single-Output (SISO) and 2×2 Multiple-Input-Multiple-Output (MIMO) systems for Car-to-Car (C2C) communication will be presented and compared. In total up to 16 possible antenna locations on the vehicle are considered and compared. A three-dimensional ray-tracing tool calculates the communication channels used for this synthesis approach. The results show that directive antenna elements, which focus in ± driving direction, can be used to increase the capacity particular in safety-critical C2C scenarios.
