What is an error???
Unpredictable change of bits from 1->0 or 0->1.
Types

  • Single bit error 8. Two Isolated bit errors:
    e(x)=xi+xj.
    e(x)=xi(1+xj-i) where i let j-i=t
    so, e(x)=xi(1+xt)
    • To catch xi the generator should have x0=1. 42. Generated Mon, 17 Oct 2016 12:06:27 GMT by s_ac15 (squid/3.5.20)

        The checker divides the codeword by the same divisor.
        This generates a remainder

        Generation of codewords for each dataword:
        C(7,4)
        n ,k
        Codeword is generated by the generator which appends 3 redundant bits at the end of the dataword.

        Its computation resembles a long division operation in which the quotient is discarded and the remainder becomes the result.

        The given dataword can be represented in polynomial terms.
        Multiply the dataword with xn-kto generate augmented dataword.
        The augmented dataword is divided by the generator polynomial g(x) and the resulting remainder Minimum Hamming Distance For Error Correction IMPLEMENTATION OF HAMMING CODE

    Remainder is also called as a syndrome.
    If the syndrome generated is 0 then there is check over here Involves error detection as well as finding the position(s) where error has occurred.

Received codeword=c(x)+e(x) where c(x) is original codeword
e(x) is the error.
The error is detected if
received codeword=c(x)+e(x) is not divisible.
Generator polynomial should be a factor of x+1.
