Quasi-cyclic LDPC (QC-LDPC) codes have been accepted as the standard codes of 5G
enhanced mobile broadband data channel. These standard codes are designed to support …

In this letter, we present an efficient method for constructing a family of quasi-cyclic low-
density parity-check (QC-LDPC) codes specified only by one single exponent matrix that can …

In this letter, we study the construction of quasi-cyclic (QC) low-density parity-check (LDPC)
codes by array dispersion and masking. We first propose a class of arrays of circulant …

The replicate-and-mask (R&M) construction of finite-length spatially-coupled (SC) LDPC
codes is proposed in this paper. The proposed R&M construction generalizes the …

This paper proposes a new low-density parity-check (LDPC) code called Matryoshka
globally-coupled (MGC) LDPC code. We give the definition of-fold MGC-LDPC code which …

In this paper, we propose a new multi-edge metric-constrained quasi-cyclic progressive
edge-growth algorithm (MM-QC-PEGA), which is suitable for constructing both single-and …

Quasi‐cyclic (QC) LDPC codes play an important role in 5G communications and have been
chosen as the standard codes for 5G enhanced mobile broadband (eMBB) data channel. In …

This paper presents two packings derived from balanced incomplete block designs to
construct quasi-cyclic spatially coupled LDPC convolutional codes (SC-LDPC-CCs). The …

In this letter, we consider the construction of q-ary low-density parity-check (LDPC) codes by
jointly optimizing the girth and number of shortest cycles in the frame of superposition. We …

Extensive studies have demonstrated the effectiveness and the flexibility of constructing
capacity-approaching codes by block Markov superposition transmission (BMST). However …
