A cyclic redundancy check (CRC) error detection scheme is constructed to generate a 4-bit frame check sequence (FCS) for an 11-bit message. The generator polynomial, P(x) = x + x2 +1(i.e., P= 11001). 1) Encode the data bit sequence M(x) = x + +1 (i.e., M=00001111001) using the generator polynomial and state the codeword. [4 Marks) 2) show that the error detection scheme at the receiver can detect the received codeword and contain no error. [3 marks]
