A construction of the high-rate regular quasi-cyclic LDPC codes
In this paper, a scheme to construct the high-rate regular quasi-cyclic low-density parity-check (QC-LDPC) codes is developed based on the finite geometry low-density parity-check (LDPC) codes.

LDPC Decoder of High Speed Multi-Rate DVB-S2 Based on FPGA
A multi-rate LDPC decoder architecture for DVB-S2 codes based on FPGA is proposed. Through elementary transformation on the parity check matrices of DVB-S2 LDPC codes, a new matrix whose left is a QC sub-matrix and right is Transformation of Staircase ...

Low-Floor Tanner Codes via Hamming-Node or RSCC-Node Doping [PDF]
We study the design of structured Tanner codes with low error-rate floors on the AWGN channel. The design technique involves the “doping” of standard LDPC (proto-)graphs, by which we mean Hamming or recursive systematic convolutional (RSC) code ...

Reordered static layered schedule for 5G low‐density parity‐check codes
A static layered schedule for the 5G low‐density parity‐check codes is proposed here. The proposed static layered schedule provides better error performance and faster convergence speed than state‐of‐the‐art. Abstract The error performance of the 5G low‐density parity‐check codes is significantly impacted by the update order of layers.

Some variations of Tanner's construction for short length QC‐LDPC codes
We propose a variation of Tanner's construction for quasi‐cyclic low‐density parity‐check codes in a way that allows us to use NON‐prime lifting sizes by using some arithmetic sequences instead of geometric sequences. We prove two theorems on the values of this lifting sizes so that the resulting code has girth at least 8.
