A code used to detect and correct errors in individual bits of transmitted data. The Hamming code adds three check (verification) bits to the end of each four bits of data. Each check bit is a calculated value representing some combination of three of the four data bits. When recalculated by the receiving device, these check bits can be used to determine whether each of the four data bits was received correctly, and they can, in some circumstances, be used to correct erroneous bits.
An error-detecting and error correcting binary code, used in data transmission, that can detect all single- and double-bit errors and correct all single-bit errors.
A code using redundant bits as a means of detecting transmission errors.
a block code capable of identifying and correcting any single bit error occurring within the block
Hamming codes are one of the most commonly used types of error correcting codes.
A Ratio-Based form of Forward Error Checking in Data Communications.
Forward error correction system used within teletext, particularly on addressing and control information. Allows recovery of single bit errors within the data byte if facility is implemented in receiver as well as detecting other forms of error.
In telecommunication, a Hamming code is a linear error-correcting code named after its inventor, Richard Hamming. Hamming codes can detect and correct single-bit errors, and can detect (but not correct) double-bit errors. In other words, the Hamming distance between the transmitted and received code-words must be zero or one for reliable communication.
