Parity-check and generator matrices for Hamming code

WebIn coding theory, a generator matrix is a matrix whose rows form a basis for a linear code. The codewords are all of the linear combinations of the rows of this matrix, that is, the linear code is the row space of its generator matrix. Terminology [ edit] If G is a matrix, it generates the codewords of a linear code C by WebThe rows of the generator matrix are the basis vectors of C. For example, the generator matrix for a 3-ary Hamming code of length 4 (n=2) is given by: > hamming_generator(2,3); Exercise 1: (a) Find a generator matrix of the binary Hamming code of length 15. (b) Find a generator matrix of the 3-ary Hamming code of length 13.
