Hamming code examples
WebIf you take this matrix as a generator matrix, the dual of the Hamming code is generated, which is called Simplex code. For example, for q = 3 and k = 3, there are 3 3 − 1 = 26 non-zero vectors in F 3 3, and a set of projective representatives consists of 26 / 2 = 13 vectors.

The code rates of Hamming codes are generated the same way as cyclic codes. In this case a parity-check length of length \(j\) is chosen, and n and k are calculated by \(n=2^j-1\) and \(k=n-j\). Hamming codes are generated first by defining a parity-check matrix \(H ...
