Abstract :
In this paper we study some fundamental properties of QC-LDPC code, we use a recursive compression algorithm to optimize the structure of QC-LDPC code, it can effectively reduce the coding complexity, save the space which is used to storage QC-LDPC code, and don´t need to reduce its error correction performance. We use VHDL language to design QC-LDPC decoder in the FPGA chip. This system was simulated in Quartus 117.2.
