Determine the BCS for the following data and CRC generating polynomials:
Data G(x) = x^7 + x^5 + x^4 + x^2 + x^1 + x^0
= 10110111
CRC P(x) = x^5 + x^4 + x^1 + x^0
= 110011
First, G(x) is multiplied by the number of bits in the CRC code, which is 5:
x^5(x^7 + x^5 + x^4 + x^2 + x^1 + x^0) = x^{12} + x^{10} + x^9 + x^7 + x^6 + x^5 = 1011011100000
Then the result is divided by P(x):
