WebA linear code of length n transmits blocks containing n symbols. 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] 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.
