One of the fec hamming code technique, which can detect and correct errors of data of any length without the redundant bit appears in a position of power as Figure 2.
Hamming Code is a technique of the FEC, which is able to detect and correct errors of any length, by which Redundant Bit is displayed in the location as being of 2 as shown.
Hamming Code is one of technical FEC which can detect and correct the errors of any information which the length by a Redundant Bit will be displayed in the office of a Woz as picture 2.
