【摘要】 Tornado码二部图构造是一个非常重要的问题。基于PEG算法构造LDPC码二部图时显现的各种优点,本文提出了一种改进的PEG构图算法。仿真结果表明,改进的算法比原PEG算法有更快的执行速度,并且基于此算法构造的Tornado码也比原始的Tornado码有更好的性能。更多还原

【Abstract】 The construction of bipartite graphs is one of very important problems in the design of Tornado codes.Based on the advantages exhibited in the construction of bipartite graph in LDPC code with PEG algorithm,an improved PEG algorithm is presented.The simulation results show that the improved algorithm has a higher executive speed compared with the original PEG algorithm and the Tornado codes which constructed with this algorithm have a better performance.更多还原
