The BER curves show that large girth and diversity level robust the system performance. Moreover, Prototype architecture of the LDPC codes has been implemented by writing Hardware Description Language (VHDL) code and targeted to a Xilinx Spartan-3E XC3S500E FPGA chip. Simulation results show that the proposed QC-LDPC codes achieve a 0.1dB coding gain over randomly constructed codes and perform 1.3 dB from the Shannon-limit at a BER of 10-6 with a code rate of 0.89 for block length of 1332. 2011-10-28T07:36:54Z 2011-10-28T07:36:54Z 2011-02-20 Working Paper p. 206-210 978-1-6128-4690-3 http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=5958912 http://hdl.handle.net/123456789/15124 en Proceedings of the IEEE Symposium on Computers and Informatics (ISCI 2011) Institute of Electrical and Electronics Engineers (IEEE)
