    • A system for use with vehicle-based wireless multiple-input multiple-output (MIMO) communications equipment has several directional sub-arrays mounted on different faces of the vehicle. It is contemplated in typical operation that each sub-array will experience different channel conditions that can be evaluated with the help of pilot tones or training sequences transmitted from a remote communications device. Based on channel rank, or other appropriate metric, the system selects the sub-array with the best predicted performance for communication with the remote device. The system achieves better MIMO performance while contributing less interference to other nearby co-channel users and allows full use of the limited number of MIMO antenna elements supported by conventional 4G wireless standards.
    • 用于基于车载无线多输入多输出(MIMO)通信设备的系统具有安装在车辆的不同面上的多个方向性子阵列。 在典型操作中可以想到,每个子阵列将经历不同的信道条件,可以借助于从远程通信设备发送的导频音调或训练序列来进行评估。 基于通道秩或其他适当的度量,系统选择具有最佳预测性能的子阵列与远程设备通信。 该系统实现更好的MIMO性能,同时对其他附近的同频道用户造成较小的干扰,并且允许充分利用传统4G无线标准支持的有限数量的MIMO天线元件。
