Hybrid Data Hiding Based on AMBTC Using Enhanced Hamming Code

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… Webber of tolerable bit errors in a code. When each two code words diﬀer in at least d min bits, one can deter-mine the number of faults that are safely detected and corrected. A decoder that exclusively detects errors, is able to detect d min − 1 erroneous bits. When the decoder corrects errors, (d min −1)/2 bit errors can be corrected. WebFeb 24, 2016 · for a) since we know that the parity bit protocol discussed can detect all 3 or less bit errors, x = 3 since Hamm(code) >= 4. We also know that in order to perform x-bit correction: Hamm(code) >= 2x + 1. Therefore we can only detect single bit errors because 2(1) + 1 = 3. Anything more would be greater than 4. can cooking with olive oil cause cancer
