信道极化与极化码的研究进展与展望

Channel Polarization and Research,Development of Polar Codes

Turbo码、LDPC码等编码技术虽然具有优越的纠错性能,但其编译码的理论基础尚不完备。而极化码由于利用了序列互信息链规则,具有丰富的代数结构与优秀的分析特性,故掀起了理论研究的热潮。综述了信道极化原理,分析了其能够达到优异性能的原因,总结了极化码目前的研究成果,指出了未来需要解决的一些关键问题。这些分析和结论对进一步研究极化码提供了理论基础和新思路。

Although the modern coding technology such as Turbo and LDPC has better correcting error per- formance, they do not have enough theory basic on coding and decoding. While polar codes have rich algebra struc- ture and excellent analysis property because of using sequence mutual information stream rule. Fundamentals of polarization were summarized and why the polar codes can analysis and conclusions provide theory basis and new train achieve the optimum performance were analyzed. The of thought.
