    ( " Single Error Correction, Double Error Detection. Coding Theory Binary Hamming Codes. The Hamming distance being 3 means that any two code words must differ in at least three bits. Hamming code is technique developed by R. Hamming for error correction. This method corrects the error by finding the state at which the. · Four check bits ( C1, C2, C3, C4) are added for error correction and detection. The check bits are computed as follows: C1. Can anyone explain me how to detect and correct errors using hamming code? Example: Construct the Hamming code word corresponding to the 4 bit string 0101. Hamming Codes - Error Detection and Error Correction. Abstract— Hamming code is familier for its single- bit error detection & correction capability. To provide such a capability, it introduces 4 redundancy bits in a 7- bit. I have a sequence of bits $ $ $ $ and need to detect two errors( without correction) using Hamming codes.
