论文摘要
本文分析了给定的区块长度的最大可实现率，并且在多 - 安特纳环境环境反向散射通道上具有完美的通道状态信息。结果由有限的区块长通道编码可实现性结合和基于Neyman-Pearson检验的匡威结合以及基于浆果定理的正常近似。这些边界的数值评估显示，随着区块长度的增加，这些边界的收敛迅速，并且还证明了通道分散是由于有限的区块长而对退出的准确度量。
This paper analyzes the maximal achievable rate for a given blocklength and error probability over a multiple-antenna ambient backscatter channel with perfect channel state information at the receiver. The result consists of a finite blocklength channel coding achievability bound and a converse bound based on the Neyman-Pearson test and the normal approximation based on the Berry- Esseen Theorem. Numerical evaluation of these bounds shows fast convergence to the channel capacity as the blocklength increases and also proves that the channel dispersion is an accurate measure of the backoff from capacity due to finite blocklength.
