Polar Codes With Repeating Bits and the Construction by Cluster Pairwise Error Probability
IEEE Access, 2019 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 ...
