论文摘要

我们考虑了准静态雷利褪色渠道中未包含随机访问的问题。在先前的工作中,作者提出了基于关节的LDPC代码解决方案,并将干扰与连续的干扰取消(TIN-SIC)解码器结构相结合。作者表明,锡 - 锡解码显着优于联合解码方法,从实施的角度来看,更简单。在本文中,我们继续对锡 - 锡解码的分析。我们使用随机编码得出了针对TIN-SIC解码器绑定的有限长度可实现的性能,并提出了基于极地代码的TIN-SIC方案。与基于LDPC代码的解决方案相比,后者的性能变得更好,并且接近有限的长度可实现性约束。

We consider a problem of unsourced random access in the quasi-static Rayleigh fading channel. In the previous work, the authors have proposed LDPC code based solutions based on joint and treat interference as noise in combination with successive interference cancellation (TIN-SIC) decoder architectures. The authors showed that TIN-SIC decoding significantly outperforms the joint decoding approach and much simpler from the implementation point of view. In this paper, we continue the analysis of TIN-SIC decoding. We derive a finite length achievability bound for TIN-SIC decoder using random coding and propose a practical polar code based TIN-SIC scheme. The latter's performance becomes significantly better in comparison to LDPC code based solutions and close to the finite length achievability bound.
