New QC-LDPC codes implementation on FPGA platform in Rayleigh fading environment
(Institute of Electrical and Electronics Engineers (IEEE), 2011-02-20)
This paper presents performance of Quasi-Cyclic low-density parity-check (QC-LDPC) codes on a flat Rayleigh fading channels by employing DPSK modulation scheme. The BER curves show that large girth and diversity level ...
A new Quasi-Cyclic low density parity check codes
(IEEE, 2009-12-16)
This paper proposes a new technique for constructing the Quasi-Cyclic low density parity check (QCLDPC) codes based on row division method. The new codes offer more flexibility in term of girth, code rates and codeword ...
