On the Concatenations of Polar Codes and Non-Binary LDPC Codes
An interleaved concatenation scheme of polar codes with non-binary low-density parity check (NBLDPC) codes is proposed in this paper to improve the error-correcting performance of polar codes with finite code length. The information blocks of inner polar

Belief Propagation Decoder With Multiple Bit-Flipping Sets and Stopping Criteria for Polar Codes
Compared with successive cancellation list (SCL) decoders, belief propagation (BP)-based decoders suffer performance loss in middle-and high-signal-to-noise ratio (SNR) regions.

Rate‐compatible systematic polar codes
Puncturing and shortening are two common ways to achieve rate‐compatible non‐systematic polar codes (NSPCs). Systematic polar codes (SPCs) have been shown to outperform NSPCs with the same encoding and decoding complexity.

Judgement of error frames using frozen bits and its applications in decoding of polar codes
Polar codes have received widespread attention because of their excellent performance. However, although successive cancellation (SC)‐based decoding algorithms have achieved excellent error correction performance, they still encounter large time delays ...

Polar Codes With Repeating Bits and the Construction by Cluster Pairwise Error Probability
A polar code with repeating bits (RB polar code), where a part of frozen bits only repeat their preceding information bits, is proposed. In the code construction, we propose cluster pairwise error probability (CPEP) to measure the competitiveness of the ...
