WebApr 3, 2024 · Before moving on, you need to have a basic understanding of Hamming code – what it is, how it is used to correct single-bit errors when transmitting data. This YouTube video might be helpful. In short, when we have a block of data with n bits, bit positions of powers of 2, i.e. 1, 2, 4, 8, 16 etc. will be used as parity bits. WebHamming Codes are linear block codes designed to detect and correct errors introduced in message bits transmitted from an end to another through a communication channel. These are single error-correcting codes that offer ease in encoding and decoding. Hamming Code falls under the category of error correction coding and is a type of cyclic code.
