Webcodewords determines how we can use code: – To detect E-bit errors: D > E – To correct E-bit errors: D > 2E – So to correct 1-bit errors or detect 2-bit errors we need d ≥3. To do both, we need d ≥4 in order to avoid double-bit errors being interpreted as correctable single-bit errors. – Sometimes code names include min Hamming ... In 1950, Hamming introduced the [7,4] Hamming code. It encodes four data bits into seven bits by adding three parity bits. As explained earlier, it can either detect and correct single-bit errors or it can detect (but not correct) both single and double-bit errors. With the addition of an overall parity bit, it becomes the [8,4] extended Hammi…
