We consider a decoding method for cyclic codes up to the Hartmann-Tzeng bound using the discrete Fourier transform. Indeed we propose how to make a submatrix of the circulant matrix from an error vector for this decoding method. Moreover an exampl...

The shift bound is a good lower bound of the minimum distance for cyclic codes, Reed-Muller codes and geometric Goppa codes. In this paper we consider cyclic codes defined by defining sequence and new simple derivation using the discrete Fourier t...
