ABSTRACT:
A data transmission method includes the steps of: a) performing two-dimensional interleaving along a time axis and along a frequency axis; b) transmitting thus-obtained data by a multi-carrier transmission form; and c) producing, by channel copy operation, data which is short with respect to the required number of channels for fast inverse Fourier transform performed antecedent and subsequent to the step a).
