Multi-carrier frequency hopping spread spectrum system with girth-six low-density parity-check codes
(Institute of Electrical and Electronics Engineering (IEEE), 2009-03-14)
In this paper, a multicarrier frequency hopping spread spectrum (MCFH-SS) system with girth-six low-density parity-check (LDPC) codes is developed as forward error correction scheme to improve its anti-jamming (AJ) ...
Row division method to generate QC-LDPC codes
(Institute of Electrical and Elctronics Engineering (IEEE), 2009-05-24)
To cut down the hardware implementation cost this paper presents an efficient method to construct large girth Quasi-Cyclic low density parity check (QCLDPC) codes. The row groups are paired two times the row weight, which ...
