Convolutional codes are encoded using a finite-state process, which generates them in a linear order encoding scheme. Subsequently, convolutional codes led to the discovery of a class of codes called Turbo codes which are the class of concatenated convolutional codes and randomized the order of some of the bits by using an interleaver. In this study, new QC-LDPC codes have been developed and then implemented to the newly designed codes on FPGA platform. Simulation results demonstrate that the proposed QC-LDPC codes achieve a 0.1dB coding gain over randomly constructed codes and perform 1.3dB from the Shannon-limit at a BER with a code rate of 0.89 for block length of 1332.
