Algorithm and Architecture for Path Metric Aided Bit-Flipping Decoding of Polar Codes
, 2019 Polar codes attract more and more attention of researchers in recent years, since its capacity achieving property. However, their error-correction performance under successive cancellation (SC) decoding is inferior to other modern channel codes at short ...

Reduced Complexity Belief Propagation Decoders for Polar Codes
, 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.

Beyond 100 Gbit/s Pipeline Decoders for Spatially Coupled LDPC Codes
EURASIP Journal on Wireless Communications and Networking, 2022 Low-density parity-check (LDPC) codes are a well-established class of forward error correction codes that provide excellent error correction performance for large code block sizes.

Network polar coded cooperation with joint SC decoding
Electronics Letters, 2015 A network polar coded‐cooperative (NPCC) scheme with joint successive cancellation (SC) decoding at the destination is proposed. Plotkin's construction is employed to build polar codes; however, the proposed construction is opposite to the conventional method where two short codes jointly construct a longer length code. In the proposed construction the

Belief Propagation Bit-Flip Decoder for Polar Codes
IEEE Access, 2019 The bit-flip method has been successfully applied to the successive cancellation (SC) decoder to improve the block error rate (BLER) performance for polar codes in the finite code length region.

Analysis of Spatially-Coupled Counter Braids [PDF]
, 2015 A counter braid (CB) is a novel counter architecture introduced by Lu et al. in 2007 for per-flow measurements on high-speed links. CBs achieve an asymptotic compression rate (under optimal decoding) that matches the entropy lower bound of the flow size ...

Analyzing Finite-length Protograph-based Spatially Coupled LDPC Codes
, 2014 The peeling decoding for spatially coupled low-density parity-check (SC-LDPC) codes is analyzed for a binary erasure channel. An analytical calculation of the mean evolution of degree-one check nodes of protograph-based SC-LDPC codes is given and an ...
