  • 摘要: 原模圖低密度奇偶校驗碼相較于傳統(tǒng)LDPC碼,具有結(jié)構(gòu)簡單、迭代譯碼門限低、易于擴展及線性編譯碼復雜度等優(yōu)點。針對強多途、長時延、窄帶寬的淺海水聲信道，該文研究了PG-LDPC碼的設(shè)計及性能特征，提出一種碼型設(shè)計方案，并采用基于原模圖度分布的外部信息轉(zhuǎn)移圖算法，對所設(shè)計PG-LDPC碼的糾錯性能進行分析及預(yù)測。仿真與實驗結(jié)果表明，與(3,6)隨機規(guī)則LDPC碼相比，所提的PG-LDPC碼在低、高信噪比區(qū)域均有良好的糾錯性能。
    Abstract: ProtoGraph-based Low Density Parity Check (PG-LDPC) codes have many advantages over the conventional LDPC codes, such as simple structure, low iterative decoding threshold, easy extension and linear encoding/decoding complexity. After investigating the characteristics of PG-LDPC codes over the Shallow Water Acoustic (SWA) channels, which have the features of strong multipath interference, long delay spreading and limited bandwidth, a new design scheme to search for good codes is proposed. Furthermore, protograph- degree-distribution-based EXtrinsic Information Transfer (EXIT) chart algorithm is used to predict and analyze the error performances of protograph-based LDPC codes. The simulation and experiment results show that the proposed code outperforms the (3, 6) randomly regular LDPC code in both low and high SNR region, over the SWA channels.
