论文摘要
在将来的无线网络中，我们预计，许多设备将通过安装在车辆上的转电（尤其是在公共交通工具中）连接到移动网络。为了提供高速移动继电器，已经提出了不同的方法，其中已经提出了不同的方法，其中预测器天线（PA）是有前途的一种。在这里，PA系统是指在车辆顶部部署两组天线的设置，并且可以使用前天线来预测在后面的天线的通道状态信息。在本文中，我们使用自适应速率分配研究了PA系统的延迟限制性能。我们使用有限的扩大长度代码可实现的速率的基本结果来研究在短数据包存在下系统吞吐量和错误概率。特别是，我们为误差概率，平均发射速率和最佳速率分配得出封闭形式的表达式，并研究不同参数对PA系统性能的影响。结果表明，在有限的块长密码字中适应速率可以提高
In future wireless networks, we anticipate that a large number of devices will connect to mobile networks through moving relays installed on vehicles, in particular in public transport vehicles. To provide high-speed moving relays with accurate channel state information different methods have been proposed, among which predictor antenna (PA) is one of the promising ones. Here, the PA system refers to a setup where two sets of antennas are deployed on top of a vehicle, and the front antenna(s) can be used to predict the channel state information for the antenna(s) behind. In this paper, we study the delay-limited performance of PA systems using adaptive rate allocations. We use the fundamental results on the achievable rate of finite block-length codes to study the system throughput and error probability in the presence of short packets. Particularly, we derive closed-form expressions for the error probability, the average transmit rate as well as the optimal rate allocation, and study the effect of different parameters on the performance of PA systems. The results indicate that rate adaptation under finite block-length codewords can impro
