Given the Pattern P = 1 1011 and the Message D= 1 1010011, find the Frame check sequence FCS using CRC 24. How many check bits are needed if the Hamming error correction code is used to detect single bit errors in a 256-bit data word? 25. Calculate the Hamming pairwise distances among the following codewords and finally the minimum Hamming distance: v2 = 010101 vl=000000 v3 = 101010 v4 110110
