Multiply the dataword with xn-kto generate augmented dataword.
The augmented dataword is divided by the generator polynomial g(x) and the resulting remainder Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. At its destination , the incoming data unit is divided by the same number.

The divisor on the receiving side divides the received code word and generates a remainder.
Remainder is also called as a syndrome.
If the syndrome generated is 0 then there is Data : 1 0 0 1 1 0 1 Data 1 0 0 1 1 0 1Adding r1 1 0 0 1 1 0 1 1Adding r2 1 0 0 1 Generated Mon, 17 Oct 2016 12:00:33 GMT by s_ac15 (squid/3.5.20) ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: http://0.0.0.7/ Connection http://fileupster.com/hamming-code/hamming-code-error-correction-example.html Positions of Redundancy Bits in Hamming Code11 10 9 8 7 6 5 4 3 2 1d d d r d d d r d r r Redundancy Bits Rutvi Shah
