Abstract

The analysis of maximal achievable rate in the finite blocklength regime provides a fundamental framework for the performance evaluation of ultra-reliable low latency communications (URLLC). This letter investigates the maximal achievable rate of multiple-antenna systems in quasi-static fading channels with finite blocklength, specifically focusing on massive uncorrelated antenna arrays and low latency scenarios. We first characterize the statistical properties of channel capacity and channel dispersion, and then derive analytical results for the maximal achievable rate. Simulation and numerical results demonstrate that the derived analytical expressions accurately characterize the performance bound of the maximal achievable rate with finite blocklength.

准静态SIMO/MIMO信道有限块长的最大可达速率

有限块长体制下的最大可达速率分析为超可靠低延迟通信（URLLC）的性能评估提供了一个基本框架。本文研究了有限块长准静态衰落信道中多天线系统的最大可实现速率，特别关注大规模不相关天线阵列和低延迟场景。我们首先描述了信道容量和信道色散的统计特性，然后推导了最大可达到速率的分析结果。仿真和数值结果表明，导出的解析表达式准确地描述了有限块长度下最大可达速率的性能界。

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
