5G
- 稀疏码多址接入,就是应5G需求设计产生的一种非正交多址技术。在发送端通过多维调制和稀疏扩频将编码比特映射成SCMA码字,接收端通过多用户检测完成译码。-Sparse code multiple access is a kind of non orthogonal multiple access technology, which should be produced by the design of 5G demand. The coding bits are mapped into SCMA

- 这是SCMA和polar编码的matlab源文件(This file is the matlab source of the SCMA and polar coded)
Deterministic Message Passing Algorithm SCMA in NOMA 5G
- Being an effective non-orthogonal multiple access (NOMA) technique, sparse code multiple access (SCMA) is promising for future wireless communication. Compared with orthogonal techniques, SCMA enjoys higher overloading tolerance and lower complexity
5G 中的 SCMA Turbo 学习
- 稀疏码多址 (SCMA) 是最近设计的一种扩展技术,其中 QAM 符号被映射到不同的 OFDMA 音调。基于码本的映射可以看作是一种扩频编码过程,其中整形增益有助于提高频谱效率并增强系统性能。本文基于 SCMA 编码方案,提出了一种联合多用户检测 (MUD) 和信道解码方法,应用了“turbo 原理”。与传统的分离检测和解码方案相比,turbo检测性能更好,增益更高,复杂度适中。在此之上,提出了一种改进方法,即在迭代之前修改外在信息。改进是基于信息的可靠性,保持可靠的信息并减少不可靠的信息。具体
