| 中文摘要: |
| 对在引信电磁感应装定中可采用的不同检验纠错码方式进行了理论分析，最终选取循环码并采用循环冗余校验法进行校验纠错。将11位信息码元进行分组，选取其中一组（110）这3个信息码元作为研究对象，求出其生成矩阵与校验矩阵，得到加入校验码后的码元组成（1100101），根据其矩阵设计出编码与解码的电路图。为了验证加入校验码后的校验效果，用MATLAB软件对（7,3）循环码在噪声情况下的传输误码率进行了仿真验证，得到的结果与理论分析结果一致。 |

| Theoretical analysis of check and error-correcting codes used in fuze electromagnetic inductive setting was carried out. The cyclic code and Cyclic Redundancy Check (CRC) were selected after the analysis.11places information code was divided into groups and one of those groups like three information code units (such as110) was selected as object of study to solve its generator matrix and check matrix; code (1100101) which had been joined in the check code was obtained; the circuit diagram was designed according to its matrix. Cyclic code (7,3) of bit error rate under the noise circumstances was verified by simulation with MATLAB software. The result comports with the theoretical analysis. |
