A heuristic construction of polar codes for successive cancellation list (SCL) decoding with a given list size is proposed to balance the trade-off between performance measured in frame error rate (FER) and decoding complexity. Furthermore, a construction based on dynamically frozen bits with ...

A CRC-aided successive cancellation list (SCL) decoding algorithm for polar codes and PAC codes with various code constructions/rate profiles. The list decoding algorithm is an adaptive two stage successive cancellation list (SCL) algorithm. First it tri
这些算法的性能经证明已经优于Turbo码和LDPC码[7-9],比如序列列表SC译码(List SC,SCL)[8-9]、堆栈SC译码(Stack SC,SSC)[10]、循环冗余校验码辅助SCL译码(CRC-SCL)[11]等算法。随着全球5G通信系统研究的展开,Polar Code也得到了学术界和国内外5G标准化研发机构的强烈关注。 1 Polar Code编码 1.1 编码原理 ...
The construction of polar codes for the Poisson channel based on Gaussian approximation is demonstrated to be accurate. The proposed scheme uses a cyclic redundancy check outer code and a successive cancellation decoder with list decoding and it is shown that it outperforms the competing schemes. ...
List Decoding of Polar Codes Channel coding is an important instrument used in communication to correct errors that occur on channels. It is interesting to find the best-suited channel code for different communication systems.Polar codes have been in the spotlight l... Emil Johansson 被引量: 30...
The complexity reduction mainly comes from the following two facts: 1)Due to the symmetric code construction, the block length reduces from N to N/2; 2) Instead of the first bit, the backtrack operation starts from the (N/2+1)-th bit, which can dramatically reduce the visited nodes. ...
