Convolutional low-density parity-check (LDPC) ensembles, introduced by Felström and
Zigangirov, have excellent thresholds and these thresholds are rapidly increasing functions …

We investigate spatially coupled code ensembles. For transmission over the binary erasure
channel, it was recently shown that spatial coupling increases the belief propagation …

In this paper, we construct protograph-based spatially coupled low-density parity-check
(LDPC) codes by coupling together a series of L disjoint, or uncoupled, LDPC code Tanner …

Quasi-cyclic (QC) low-density parity-check (LDPC) codes are an important instance of proto-
graph-based LDPC codes. In this paper we present upper bounds on the minimum …

Low-density parity-check (LDPC) convolutional codes are capable of achieving excellent
performance with low encoding and decoding complexity. In this paper, we discuss several …

Cyclic liftings are proposed to lower the error floor of low-density parity-check (LDPC) codes.
The liftings are designed to eliminate dominant trapping sets of the base code by removing …

Recently, it was observed that spatially-coupled LDPC code ensembles approach the
Shannon capacity for a class of binary-input memoryless symmetric (BMS) channels. The …

We discuss error floor asympotics and present a method for improving the performance of
low-density parity-check (LDPC) codes in the high SNR (error floor) region. The method is …

Low-density parity-check (LDPC) convolutional codes have been shown to be capable of
achieving capacity-approaching performance with iterative message-passing decoding. In …

Spatially coupled turbo-like codes (SC-TCs) have been shown to have excellent decoding
thresholds due to the threshold saturation effect. Furthermore, even for moderate block …
