Abstract(in English) | It is shown that generalized discrete Fourier transform codes as an Abelian code can be constructed from multilevel block codes. This Fourier transform codes hold the convolution property, conjugate symmetry property and other properties in a similar way of Fourier transform codes constructed over Galois field. The conceptual multilevel block codes of Fourier transform codes are constructed from QPSK modulated multilevel codes of codelength 9, 8-PSK modulated multilevel codes of codelength 49, 16-QAM modulated multilevel codes of codelength 15 and 25. Finally, it is considered that the bit shift periodcity of Fourier transform codes can be explained as a cyclic generator matrix of multilevel component codes. |
