Homework Help: CRC Example

  1. Mar 5, 2008 #1
    Consider a message D, presented by the following polynomial
    x19 +x17 + x16 +x13 +x12 + x11 + x9 + x5 + x2 + 1
    Calculate the CRC code R for that message using a “generator-polynomial”
    x7 + x5 + x4 + x3 + x2 + 1.
    Represent in binary code the message to be sent (D and R).
    Generate 3-bit burst error and show the checking procedure (10 points)

    D = 10110011101000100101
    G = 10111101

    Divide using XOR

    Added 7 0's to D


    Transmitted message = 10001100101010110101
    R= 111001

    Now I need to generate a 3-bit burst error and I assume that could be anywhere. How do I show the check procedure?
