For example, the [7,4,3] Hamming code is a linear binary code which represents 4-bit messages using 7-bit codewords. Two distinct codewords differ in at least three bits. As a consequence, up to two errors per codeword can be detected while a single error can be corrected. [3]

WebJun 6, 2024 · The Binary Hamming code Using the idea of creating parity bits with the XOR operator, we can create what is called the Hamming [7, 4] -code. We will combine multiple bits to create each of the parity bits for this code. This code will take in a four-bit input and encode it into a seven-bit codeword. WebHamming code is a special code in a Computer network, which is a set of error-correction codes. In Computer Graphics, it is mainly used for detecting and correcting errors that occur at the time of data transmission from sender to receiver. In Java, we can implement the code to detect and correct errors using Hamming code.
