摘　　要：引信的装定过程需要对时间信息进行数字编码,以保证数据传输的有效性和抗干扰能力,而在接收时需要对编码信号进行译码和纠错。介绍了GF(7,4)Hamming码的理论基础,分析了其编码译码过程,利用Matlab编程对编码、译码过程进行了仿真分析,并验证了Hamming码实现检错和纠错的能力,从而证明了其作为信道编码方法的有效性。The fuse setting process requires encoding of the time information to guarantee the effectiveness and capabili‐ty of anti‐interference ,and decoding and error correction needs to be undertaken when the code is received .A brief introduc‐tion to the theoretical principle of （7 ,4） Hamming code is given ,and the encoding and decoding process is introduced .Simu‐lations are undertaken aided by Matlab program to study on the encoding and decoding process ,which verifies the ability of Hamming code to detect and correct errors ,thus proving its effectiveness to serve as a method of channel encoding .

关 键 词：引信装定 Hamming码 编码译码 纠错
