Quiz 1 (10 points)

 

Name:

 

CRC (Cyclic Redundancy Check) Code = Polynomial Code

 

Suppose that

 

(1)   k = 5, n–k = 3,

(2) Generator polynomial:  g(x)= x3 + x + 1

(3) Information: (1,1,0,0,1) 

 

 

 

1.    (2 points) What is the polynomial representation of the binary information vector (1,1,0,0,1) ?

 

 

 

2.    (8 points) What is the transmitted codeword?  You must show the intermediate calculation which leads you to the solution.  Show the transmitted codeword in a polynomial representation and a binary vector representation.

G NOTE:

An answer without showing the intermediate calculation (i.e., explanation) will consider as an incorrect answer.
