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 code methods and also parity bits are coded with hamming codes. Whereas in decoder ...
The (n, n − 1) binary single parity-check code can be constructed by taking any sequence of n − 1 information bits, and appending to them a parity-check bit which is their sum mod 2. To view the (7, 4) binary Hamming code as a parity-check code, label the symbols of each...
