Question

Answer following questions related to error detection. a- In a tranmission, sender system a sent frame including FCS bits as 1 0 1 1 1 0 0 0 1 1 1 0 1 Which of the following G(x) polynom is used CRC algorithm? Prove it. G(x) = x^4+x^2+1 G(x) = x^3 + x + 1 b- if receiver system received the frame as 1 0 1 1 0 1 0 0 0 1 1 0 1, what will be the result of detection process? Prove it. c- In tranmission, instead of CRC which type of parity check could detect the error occurred in data part on received data? Why?

Explanation / Answer

1)

g = x^4+x^2+1

3)  trivial 1-bit CRC
