According to the limitation of resources on satellite, this paper focuses on the design and realization of low complexity LDPC decoder. A new implementation method of LDPC decoder is proposed, a various kinds of LDPC codes could be supported. Finally, a (4096, 2048) LDPC decoder is implemented for verification based on a Xilinx Vertex4 xc4vsx35 FPGA platform. The implementation result shows that only 4% FPGA logic resources were consumed and the maximum clock frequency could achieve 180MHz.
