Reduced complexity belief propagation decoders for polar codes [PDF]
2015 IEEE Workshop on Signal Processing Systems (SiPS), 2015 Polar codes are newly discovered capacity-achieving codes, which have attracted lots of research efforts. Polar codes can be efficiently decoded by the low-complexity successive cancelation (SC) algorithm and the SC list (SCL) decoding algorithm. The belief propagation (BP) decoding algorithm not only is an alternative to the SC and SCL decoders, but ...

A Novel Variable-Order Threshold Serial Belief Propagation-Based Decoding Algorithm for LT Codes
IEEE AccessThe belief propagation (BP) algorithm is a widely adopted iterative decoding method for Luby transform (LT) codes. However, the conventional log-likelihood ratio BP (LLR-BP) decoder exhibits inherent limitations in additive white Gaussian noise (AWGN ...

The effect of saturation on belief propagation decoding of LDPC codes [PDF]
2014 IEEE International Symposium on Information Theory, 2014 We consider the effect of LLR saturation on belief propagation decoding of low-density parity-check codes. Saturation occurs universally in practice and is known to have a significant effect on error floor performance. Our focus is on threshold analysis and stability of density evolution. We analyze the decoder for certain low-density parity-check code
