| Abstract(in English) | Low Density Parity Check (LDPC) code is expected to be an error correcting code for next generation networks since it shows high error correcting performance and is incorporated into IEEE802.11n, the next standard of wireless network. In this paper, we propose a multi-rate compatible irregular LDPC decoder enhancing column operation parallelism. Focusing on column-wise parallelism of column operations, our LDPC decoder increases usage rate of operational units and throughput by calculating all inputs simultaneously. The decoder achieves 28% increase in throughput compared to resent architectures. |
