Low-Complexity Real-Time LDPC Encoder Design for CMMB

  title={Low-Complexity Real-Time LDPC Encoder Design for CMMB},
  author={Peng Wang and Yong-en Chen},
  journal={2008 International Conference on Intelligent Information Hiding and Multimedia Signal Processing},
Based on modified LU decomposition theory with pivoting of sparse matrix, a low-complexity real-time LDPC encoder for CMMB was presented, which can support 2 different code rate (1/2 and 3/4). Multi- staged pipeline and Pingpong buffer architectures were used to improve throughput. An efficient memory organization for storing sparse matrices was also presented. Whole design was synthesized and routed on Altera Stratix II EP2S90. Highest frequency achieved over 200 MHz, with pure encoding rate… CONTINUE READING
