在用于MIMO无线通信的发射和接收天线阵列中使用多个天线允许利用丰富散射环境中的空间自由度。然而，对于在发射器和接收器处具有均匀线性阵列（ULA）的视线（LOS）MIMO信道，需要优化发射和接收阵列处的天线间隔以最大化空间自由度和信道容量。本文首先对LOS MIMO系统中发射和接收ULA处的最佳天线间距进行了推导，给出了最佳天线间距乘积的一般表达式，该表达式包含多个解。虽然只有对应于最小的天线分离产品的解决方案通常被认为是在文献中，我们利用多个解决方案的LOS MIMO设计在发射机和接收机之间的距离范围。特别是，我们认为LOS MIMO设计中的车辆到车辆（V2V）通信的情况下，在发送和接收车辆之间的距离范围。
The use of multiple antennas in a transmit and receive antenna array for MIMO wireless communication allows the spatial degrees of freedom in rich scattering environments to be exploited. However, for line-of-sight (LOS) MIMO channels with uniform linear arrays (ULAs) at the transmitter and receiver, the antenna separations at the transmit and receive array need to be optimized to maximize the spatial degrees of freedom and the channel capacity. In this paper, we first revisit the derivation of the optimum antenna separation at the transmit and receive ULAs in a LOS MIMO system, and provide the general expression for the optimum antenna separation product, which consists of multiple solutions. Although only the solution corresponding to the smallest antenna separation product is usually considered in the literature, we exploit the multiple solutions for a LOS MIMO design over a range of distances between the transmitter and receiver. In particular, we consider the LOS MIMO design in a vehicle-to-vehicle (V2V) communication scenario, over a range of distances between the transmit and receive vehicle.
