Searching for low weight pseudo-codewords
— Belief Propagation (BP) and Linear Programming (LP) decodings of Low Density Parity Check (LDPC) codes are discussed. We summarize results of instanton/pseudo-codeword approach...

Analysis of Quasi-Cyclic LDPC codes under ML decoding over the erasure channel
In this paper, we show that over the binary erasure channel, Quasi-Cyclic LDPC codes can efficiently accommodate the hybrid iterative/ML decoding. We demonstrate that the quasicycl...

Rateless Coding for Gaussian Channels
— A rateless code—i.e., a rate-compatible family of codes—has the property that codewords of the higher rate codes are prefixes of those of the lower rate ones. A perfect fa...

A Split-Decoding Message Passing Algorithm for Low Density Parity Check Decoders
A Split decoding algorithm is proposed which divides each row of the parity check matrix into two or multiple nearly-independent simplified partitions. The proposed method signific...
