BCH码的编译码算法依据的原理，并且实现了BCH (15, 5)码的仿真。该码码长n=15, 信息码位k=5, 纠错位t=3, 阶数m=4, 能纠错3位。译码所用的方法是彼得森译码方法。在彼得森一码中采用计算校正子，然后用校正子寻找错误图样的方法。-BCH code encoding and decoding algorithm based on the principle, and BCH (15, 5) code of the simulation. The code code length n = 15 information code k = 5, error correction bits t = 3, the order of m = 4, can error correction 3. The method is used in decoding the Peterson decoding method. Adopted to calculate the correction sub-one yards Petersen, then corrector find the error pattern.
