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。

This section contains a brief introduction to the C language. It is intended as a tutorial on the language, and aims at getting a reader new to C started as quickly as possible. It is certainly not intended as a substitute for any of the numerous textbooks on C. 2. write a recursive function FIB (n) to find out the nth element in theFibanocci sequence number which is 1,1,2,3,5,8,13,21,34,55,…3. write the prefix and postfix form of the following infix expressiona + b – c / d + e * f – g * h / i ^ j4. write a function to count the number of nodes in a binary tr
