Abstract

We have designed and implemented the LDPC decoder with memory-reduction method to achieve high-throughput and practical hardware size for long code-length. The decoder decodes (3,6)-11520-rbit regular LDPC codes using modified minsum algorithm. The decoder achieves a throughput of 312 Mb/s at an operating frequency of 69 MHz with 20 iterative decoding. The gate count is 2M gates.
