Hamming Codes are used for detecting multiple errors in a transmitted code. It can trace missing parts of a code that may have been lost through transmission and it can also tell you if an error has occurred in any bit of the code using Modulo Tow Arithmetic.

Hamming code handles only single-bit errors-two or more errors will cause an incorrect syndrome value. It can detect double bit error but not corrected
i want hamming code matrix (h and g)
Hamming Code for A: 010010000100 (The strike numbers are the check bits) Hamming Code for 3: 001100011101
Hamming code is only used for single bit error :/
assume that u have received a code, you multiply it to parity check matrix and it results to syndrome, the syndrome identify you the error code from table look up which can be made by multiplying any probable error pattern in generator matrix.
In computer organisation ...what is hamming code.?
the code 11110101101 was received using hamming encoding algorithm what was the original code sent
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.
you need thee extra bit for 4 bit data in hamming code.
Go to school!
hamming code between 1000110 and 1110100 can be calculated by just exoring both codes with each other as follow: 1000110 1110100 ------------ 0110010 now by counting the ones in the result that gives 3 then hamming dictance = 3
In CRC, the redundant bits are derived from binary division to the data unit. While in hamming code, the redundant bits are a function of length of the data bits.
