Abstract(in English) | In this paper we propose an efficient Message-Passing schedule which is suitable for irregular LDPC decoder. For the decoding matrix of high column degree, our proposed decoder can complete all the column omerations which is relate to intermediate messages updated by row operations. We compare the performances of proposed schedule and conventional schedule based on irregular parity check matrixes in IEEE 802.11n protocol. We design the irregular LDPC decoder using TSMC 0.18μm CMOS technology. According to the synthesis results, our proposed decoder doubles the throughput by consuming 36% larger area, compared with the conventional decoders. |
