面向6G的极化码与极化处理

Polar codes and polar processing for 6G wireless systems

作为第一种达到信道容量的高性能编码,极化码是未来6G数据传输的重要候选方案。为此提出了面向6G的极化处理框架。在此框架下,设计高性能的级联极化编码方案,可以逼近有限码长信道容量极限,符合6G超高可靠传输要求。进一步,设计极化编码MIMO方案可以匹配6G高频谱效率传输需求;设计极化编码非正交多址方案能够满足6G大容量传输需求。这些方案表明,极化处理能够显著提升6G无线传输性能,具有广阔的应用前景。

As the first type of channel code achieving the channel capacity,polar codes are an important candidate for the 6G data transmission.A polarized processing framework for the 6G systems was proposed.In this framework,in order to fulfill the requirement of ultra-reliable transmission,a high-performance coding scheme of concatenated polar code was designed to approach the channel capacity with finite-length.Then,the polar coded MIMO scheme was devised to match the requirement of the high spectrum efficiency.Finally,the scheme of polar coded non-orthogonal multiple access was investigated to improve the transmission capacity.All these schemes indicate that polar processing can dramatically boost the performance of 6G wireless transmission and become a promising direction.
