摘要
二元BCH码是一种纠错能力极强的好码,具有良好的代数结构和纠错能力,可以用循环移位寄存器来设计其编码器和译码器.对于BCH(15,5,7)的突发错误,本文采用捕错译码算法,设计了BCH(15,5,7)码的一种高效可行的译码器,其电路设计行之有效,纠错能力强,在通信系统中可以提高通讯数据传输的准确性,具有一定的现实意义和应用前景.
Binary BCH codes are a very important kind of linear cyclic error-correcting code which can correct many random errors and have a series of strongpoint such as their good algebra structure and powerful correction abilities. We can design its coder to catch sudden mistakens for the BCH（15,5,7）. its electric circuit is effective,and correct ability is strong. It can raise the accuracy of communication data.They are widely used in digital communication,therefore,study of decoding algorithm of binary BCH codes have important meanings no matter in practice or theory.
