Design and Implementation of Universal LDPC Code Encoder in the DVB-S2 Based on FPGA

研究了一种用FPGA实现DVB-S2标准的LDPC码高速通用编码器的设计方法。设计采用流水线技术和全并行结构相结合的方法,提高了编码效率。FPGA仿真结果和综合报告表明,设计的LDPC码编码器具有通用性,能够针对DVB-S2中两种码长、11种码率的LDPC码进行编码,且时钟频率达到了114MHz,适用于DVB-S2标准。

This paper describes a design method of universal high-speed LDPC code encoder in the DVB-S2 using FPGA. The design method, combining pipelining technique with parallel structure, has realized universal LDPCcode encoder , and improved the efficiency of encoder. FPGA report shows that the encoder accords with the demands for LDPC code of two code lengths and eleven code rates in DVB-S2 standard and can be used by the standard.
