论文摘要
本文研究了给定的平均误差概率和可重新配置智能表面（RIS）辅助多输入和多输出（MIMO）系统的最大可实现率。结果由有限的区块长的通道编码可实现性结合和基于浆果 - 埃森定理，梅林变换和互信息的相反结合。数值评估显示，随着区块长度的增加，收敛速度的快速速度与最大可实现的速度相关，并且还证明了通道方差是由于有限的块长而引起的最大可实现率的向退回率的声音测量。
This paper investigates the maximal achievable rate for a given average error probability and blocklength for the reconfigurable intelligent surface (RIS) assisted multiple-input and multiple-output (MIMO) system. The result consists of a finite blocklength channel coding achievability bound and a converse bound based on the Berry-Esseen theorem, the Mellin transform and the mutual information. Numerical evaluation shows fast speed of convergence to the maximal achievable rate as the blocklength increases and also proves that the channel variance is a sound measurement of the backoff from the maximal achievable rate due to finite blocklength.
