Abstract

A method for forming the virtual aperture of a multiple-input–multiple-output (MIMO) antenna array with a random arrangement of elements is proposed. For this purpose, the required number of receiving (Rx) and transmitting (Tx) elements is placed independently of each other within a given area so that they do not overlap with each other. The coordinates of the elements have an equally probable distribution. Based on these coordinates, the virtual aperture of the MIMO antenna array is formed. For a virtual aperture, the characteristics of its radiation direction multiplier are evaluated, that is, the width of the main lobe and the peak level of the sidelobe. Based on the resulting characteristics of the radiation direction multiplier, the distribution of Rx and Tx elements is optimized using a genetic algorithm to achieve the required directional properties of the virtual aperture. An example of virtual aperture MIMO antenna array synthesis with a random arrangement of elements is presented, consisting of 30 Rx and 30 Tx elements.

具有提供指定方向特性的随机单元排列的MIMO天线阵列

提出了一种元件随机排列的多输入多输出（MIMO）天线阵的虚拟孔径形成方法。为此，在给定的区域内，所需数量的接收（Rx）和发送（Tx）元件相互独立地放置，以使它们不相互重叠。元素的坐标具有等概率分布。基于这些坐标，形成了MIMO天线阵的虚拟孔径。对于虚拟孔径，评估了其辐射方向乘法器的特性，即主瓣的宽度和副瓣的峰值电平。基于得到的辐射方向乘法器的特性，利用遗传算法优化Rx和Tx元素的分布，以获得所需的虚拟孔径方向特性。给出了一种由30个Rx和30个Tx单元组成的随机单元组合的虚拟孔径MIMO天线阵列的实例。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
