Description: 循环冗余校验CRC (Cyclic Redundancy Check)码是由分组线性码的分支而来,其主要应用是二元码字。编码简单且误判概率很低,在通信系统中得到了广泛的应用。循环冗余校验码是属于分组码中的一类重要的线性码,它不仅在理论上具有很好的代数结构,而且其编码和译码可以通过线性移位寄存器很容易地实现。
通过对CRC的分析和基于MATLAB工具的仿真,充分证明了CRC的检错能力很强,编码简单。
-Cyclic Redundancy Check CRC (Cyclic Redundancy Check) code is a linear code from the sub-branch from the main application is the binary code word. Coding is simple and very low probability of miscarriage of justice, in the communication system has been widely used. Cyclic redundancy check code is a block code in one important class of linear code, which not only has good in theory, algebraic structure, and its encoding and decoding of linear shift register can easily realize . CRC through analysis and simulation tool based on MATLAB, and fully proves that the CRC error detection ability of a strong, simple coding. Platform: |
