预测天线系统:利用车辆通信的信道状态信息

Predictor Antenna Systems: Exploiting Channel State Information for Vehicle Communications

Hao Guo

摘要:

车辆通信是第五代无线网络(5G)中最重要的用例之一。对以诸如频谱效率、峰值数据率和中断概率的性能度量为特征的服务质量(QoS)的不断增长的需求主要受到移动车辆周围快速变化的环境的信道状态信息(CSI)的不准确预测/估计的限制。为了提高QoS,增加CSI的预测范围的一种方式是部署预测器天线(PA)。PA系统由通常安装在车辆车顶上的两组天线组成,其中位于车辆前部的PA用于预测由在PA后面对准的接收天线(RA)观察到的CSI。然而,在现实的PA系统中,实际的益处受到各种因素的影响,包括空间失配、天线利用率、散射环境的时间相关性以及CSI估计误差。本文研究了在实际条件限制下PA系统的不同资源分配方案。

英文摘要:

Vehicle communication is one of the most important use cases in the fifth generation of wireless networks (5G). The growing demand for quality of service (QoS) characterized by performance metrics, such as spectrum efficiency, peak data rate, and outage probability, is mainly limited by inaccurate prediction/estimation of channel state information (CSI) of the rapidly changing environment around moving vehicles. One way to increase the prediction horizon of CSI in order to improve the QoS is deploying predictor antennas (PAs). A PA system consists of two sets of antennas typically mounted on the roof of a vehicle, where the PAs positioned at the front of the vehicle are used to predict the CSI observed by the receive antennas (RAs) that are aligned behind the PAs. In realistic PA systems, however, the actual benefit is affected by a variety of factors, including spatial mismatch, antenna utilization, temporal correlation of scattering environment, and CSI estimation error. This thesis investigates different resource allocation schemes for the PA systems under practical constraints.
