Effectiveness Analysis of QC-LDPC Encoder with Model Based Design Approach

Channel coding techniques are used to reduce error rates during data transmission in mobile communication systems. LDPC (Low-density Parity Check) coding was first designed by Robert G. Gallager in 1962. It has been accepted and started to be used as a standard for coding data channels in fifth generation mobile communication by member companies of 3GPP (3rd Generation Partnership Project). The QC-LDPC method, which has a more hardware-friendly algorithmic structure, was chosen by 3GPP as the coding method. In this study, the QC-LDPC coding block, which is clearly stated in the 3GPP TS 38–212 standard document, is model-based and implemented on the FPGA.
