Abstract
In a method and/or an OFDM device for SC-FDMA data transmission, a sequence of input data is transformed by means of a discrete transformation as transformed data signals of coded and modulated data signals on first frequency channels into a first frequency space over a first number of frequencies. The transformed data signals are mapped on second frequency channels in a second frequency space with a larger second number of frequencies. The transformed data signals on the second frequency channels are inverse-transformed using an inverse transformation. Data inversely transformed in such a way are provided for transmission. The transformed data signals are mapped into a frequency range of the second frequency channels in such a way that a constant component of the transformed data signals is mapped centrally within the frequency range.
