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 in 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, uplift usage rate of operational unit and throughput by calculating all inputs simultaneously. The decoder achieves 12% savings in area and 81% increase in throughput compared to recent architectures. |
