LDPC Codes from Triangle-Free Line Sets
We study sets of lines of AG(n, q) and PG(n, q) with the property that no three lines form a triangle. As a result the associated point-line incidence graph contains no 6-cycles a...

High-rate quasi-cyclic LDPC codes for magnetic recording channel with low error floor
— By implementing an FPGA-based simulator, we investigate the performance of high-rate quasi-cyclic (QC) LDPC codes for the magnetic recording channel at very low sector error ra...

Low-Complexity List-Based Frame Synchronization for LDPC Coded Transmission
Abstract—In this paper, we propose a simple and efficient twostage list synchronizer for frame synchronization of Low-Density Parity-Check (LDPC) coded data transmitted over the...

Protograph LDPC Codes with Node Degrees at Least 3
— In this paper we present protograph codes with a small number of degree-3 nodes and one high degree node. The iterative decoding threshold for proposed rate 1/2 codes are lower...

A Parallel and Modular Architecture for 802.16e LDPC Codes
We propose a parallel and modular architecture well suited to 802.16e WiMax LDPC code decoding. The proposed design is fully compliant with all the code classes defined by the Wi...
