Optimized Design of Distributed Quasi-Cyclic LDPC Coded Spatial Modulation [PDF]
We propose a distributed quasi-cyclic low-density parity-check (QC-LDPC) coded spatial modulation (D-QC-LDPCC-SM) scheme with source, relay and destination nodes. At the source and relay, two distinct QC-LDPC codes are used.

A construction for girth‐8 QC‐LDPC codes using Golomb rulers
In this paper, an algebraic construction of regular QC‐LDPC codes by using the modular multiplication table mod P and Golomb rulers are proposed. It is proved that the proposed QC‐LDPC codes based on a Golomb ruler of length L have girth at least 8 if P ...

Constructing LDPC Codes with Any Desired Girth [PDF]
In wireless sensor networks, the reliability of communication can be greatly improved by applying low-density parity-check (LDPC) codes. Algorithms based on progressive-edge-growth (PEG) pattern and quasi-cyclic (QC) pattern are the mainstream approaches

On a class of column‐weight 3 decomposable LDPC codes with the analysis of elementary trapping sets
A column‐weight k LDPC code with the parity‐check matrix H is called decomposable if there exists a permutation π on the rows of H, such that π(H) can be decomposed into k column‐weight one matrix.

Full-Length Row-Multiplier QC-LDPC Codes With Girth Eight and Short Circulant Sizes
As a special case of a quasi-cyclic (QC) low-density parity-check (LDPC) code, a full-length row-multiplier (FLRM) QC-LDPC code is described by a compact exponent matrix based on two sequences of integers.

Area‐ and energy‐efficient high‐throughput QC‐LDPC encoder for space applications
An area‐ and energy‐efficient encoding method and encoder architecture are proposed using a bit selector before bit XOR operations in vector–matrix multiplication. A fully parallel low‐density parity check encoder is implemented on the aiwan Semiconductor Manufacturing Company (TSMC) 90 nm complementary metal oxide semiconductor (CMOS) technology ...
