Here various error detection and correction methods are implemented based on parity check code along with hamming code algorithm. Encoder block may calculate the parity bits for data bits in various parity check
Hamming codes are a class of single error-correction codes, characterized by having a codeword length of Kc = 2q − 1 and a message length of Kb = 2q − 1 − q for any integer q = Kc − Kb [13]. From: Academic Press Library in Mobile and Wireless Communications, 2016 ...
Here is theC source code library for Hamming 24,16 error-correcting code (ECC). It includes both the ECC generator, as well as the detection/correction routines.

Single Bit Error Detection and Correction Using Novel Hamming Code MethodThese days error free transmission of data is a key challenge in data transmission. This can be achieved by using various error detecting and correcting codes like Automatic Repeat Request (ARQ), Forward Error Correction (FEC)...
Create Hamming code from binary vector data Library Block sublibrary of Error Detection and Correction Description The Hamming Encoder block creates a Hamming code with message lengthKand codeword lengthN. The numberNmust have the form 2M-1, whereMis an integer greater than or equal to 3. Then...
Decode Hamming code to recover binary vector data Library Block sublibrary of Error Detection and CorrectionDescription The Hamming Decoder block recovers a binary message vector from a binary Hamming codeword vector. For proper decoding, the parameter values in this block should match those in the ...
The simplicity of hamming codes makes them suitable for use in computer memory and single-error correction. They use a double-error detection variant called SECDED. These codes have a minimum hamming distance of three, where the code detects and corrects single errors while double bit errors are...
In Section 2, the VQ attack, which is a security problem, is briefly described. The logistic map (a chaotic map) and Hamming code technologies are then introduced. In Section 3, the proposed fragile watermarking scheme, including the embedding and detection procedures, is presented. Section 4 ...
LeetCode "477. Total Hamming Distance" Fun one.. the punch line of this problem is quite common in Bit related problems on HackerRank - visualize it in your mind, and you will find: all bits on the same index among all numbers, will not involve other bits on other indices. So, we ...
