2. [2] Suppose we receive a bit sequence: 100001110101011100010011. Suppose a (3,1) repetition code is used. a) What is the original message bit sequence? b) What is the code rate? 3. [4] A two-dimensional parity checking table is shown below. Assume that even parity is used and the receiving codeword is [DI D2 D3 D4 P1 P2 P3 P4). A parity bit is added for each row and for each column as shown in the table below. D1 D2 P1 P2 D3 D4 P3 P4 For each received codeword in a) to d), please indicate: • Correction: a single bit error occurs (give the position of the bit that needs correcting e.g. D4) • No error! Cannot correct, there are multiple errors. a) [00110101] b) [11011010] c) [10101001] d) [01011100)
