An Improved
IEEE Access, 2018 Comparing with hard decision decoding algorithms, soft decoding has a lower probability of bit error but a higher computational complexity. As a maximum-likelihood soft decoding method, the A* algorithm is the most basic and widely used to minimize bit ...

SCF Decoding Algorithm Based on Log Likelihood Ratio and Channel Polarization Reliability [PDF]
Jisuanji gongcheng, 2022 The traditional Successive Cancellation bit-Flipping(SCF) decoding algorithm only uses the absolute value of Log Like Ratio(LLR) to measure the reliability of information bit decoding results, which leads to a high Block Error Rate(BLER) and more ...

Simple algorithms for BCH decoding [PDF]
IEEE Transactions on Communications, 1995 Summary: Some simple algorithms for decoding BCH codes are proposed. We show that the pruned FFT is an effective method for evaluating syndromes and for finding the roots of error-locator polynomials. We show that a simple variation of the basic Gaussian elimination procedure can be adapted to compute the error-locator polynomial efficiently for codes ...
