Description: 在远距离数据通信中，为确保高效而无差错地传送数据，必须对数据进行校验即差错控制。循环冗余校验CRC(Cyclic Redundancy Check/Code)是对一个传送数据块进行校验，是一种高效的差错控制方法。-in long-distance data communication, in order to ensure efficient without error to transmit data, the data must check that the error control. Cyclic Redundancy Check (Cyclic Redundancy Check/Code) is to block transmission of data over a check out, is a highly efficient error control methods. Platform: |

Description: crc任意位生成多项式 任意位运算 自适应算法 循环冗余校验码(CRC，Cyclic Redundancy Code)是采用多项式的 编码方式，这种方法把要发送的数据看成是一个多项式的系数 ，数据为bn-1bn-2…b1b0 (其中为0或1)，则其对应的多项式为： bn-1Xn-1+bn-2Xn-2+…+b１X+b０ 例如：数据“10010101”可以写为多项式 X７+X４+X２+1。 循环冗余校验CRC 循环冗余校验方法的原理如下： (1) 设要发送的数据对应的多项式为P(x)。 (2) 发送方和接收方约定一个生成多项式G(x)，设该生成多项式 的最高次幂为r。 (3) 在数据块的末尾添加r个0，则其相对应的多项式为M(x)=XrP(x) 。(左移r位) (4) 用M(x)除以G(x)，获得商Q(x)和余式R(x)，则 M(x)=Q(x) ×G(x)+R(x)。 (5) 令T(x)=M(x)+R(x)，采用模2运算，T(x)所对应的数据是在原数 据块的末尾加上余式所对应的数据得到的。 (6) 发送T(x)所对应的数据。 (7) 设接收端接收到的数据对应的多项式为T’(x)，将T’(x)除以G(x) ，若余式为0，则认为没有错误，否则认为有错-crc-generating polynomial arbitrary arbitrary Operators adaptive algorithm Cyclic Redundancy Check (CRC. Cyclic Redundancy Code) is the polynomial coder, This way the data to be sent as a polynomial coefficient data bn- 1bn-2 ... b1b0 (0 or 1), corresponding to the polynomial : bn- 1Xn-1 bn- 2Xn-2 ... b1X belts such as : data "10010101" polynomial can be written as a X7 X4 X2. Cyclic Redundancy Check Cyclic Redundancy Check method of principle as follows : (1) The data to be sent to the corresponding polynomial p (x). (2) the sender and the receiver agreed on a generator polynomial G (x), set up the generator polynomial of the highest power of r. (3) In the data block Add to the end of r-0, then the polynomial corresponding to M (x) = XrP (x). (R-bits) (4) M (x) divided by G ( Platform: |

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: |

Description: CRC即循环冗余校验码（Cyclic Redundancy Check[1] ）：是数据通信领域中最常用的一种查错校验码，其特征是信息字段和校验字段的长度可以任意选定。循环冗余检查（CRC）是一种数据传输检错功能，对数据进行多项式计算，并将得到的结果附在帧的后面，接收设备也执行类似的算法，以保证数据传输的正确性和完整性。-CRC is the most commonly used in the field of data communication error check code, which is characterized by the information field and the length of the check field can be arbitrarily selected. Cyclic Redundancy Check (CRC) is a data transmission error detection function, the data is polynomial calculation, and the results will be attached to the back of the frame, the receiving device also performs a similar algorithm to ensure the correctness and integrity of the data transmission Sex.
