摘要:
The invention relates to a method and/or an OFDM device for SC-FDMA data transmission in which a sequence of input data (x(i), i = 1, 2, 3,..., N) is transformed by means of a discrete transformation (DFT) as transformed data signals (yi, i = 1, 2, 3,..., N) of coded and modulated data signals on first frequency channels (f1, f2, f3,..., fN) into a first frequency space over a first number of frequencies (N), the transformed data signals (yi) are mapped on second frequency channels (f1*, f2*, f3*,..., fN *,...., fNc*) in a second frequency space with a larger second number of frequencies (Nc), the transformed data signals on the second frequency channels are inverse-transformed using an inverse transformation (IFFT), and data (zi) inversely transformed in such a way are provided for transmission. On this basis, the transformed data signals (yi) are mapped into a frequency range (fi+1*,..., fi+N*) of the second frequency channels in such a way that a constant component (y1, f1) of the transformed data signals (yi) is mapped centrally within the frequency range (fi+1*,..., fi+N*).
