Abstract
PURPOSE: To detect the error in information bits, by assigning d1,d2...dr by every one bit to the r sets of groups Gn-p+i...Gn with the code having known dode length n, information point n-r and inspection point r and by taking them as the check bit for the information bits a1,a2...am.
CONSTITUTION: The handle decoder 12 is grouped into n sets of groups G1,G2...Gn so that the information bits of m sets a1,a2...am having different weighting for a part or all can constitute one group with less number to greater weighting bit. Further, the hamming coder 11 assigns d1,d2...dr by one bit to the r sets of groups Gn-p+i... Gn corresponding to the inspection point with the code having known code length n, information point n-r, and inspection point r according to the representative bits e1,e2...en-r and is determined with di so that "1" and "0" determined with the odd or even number of "1" or "0" can be in agreement with fi when one group is made with Gn-r+i and di(i=1,2...r). This di can detect the error in the information bit.
