One simple way to achieve the centering is to use a 2N-IFFT [2] and T/2 as the elementary period. As we can see in Table 1, the OFDM symbol ...
A fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa. The DFT is obtained by decomposing a sequence of values into components of different frequencies. This operation is useful in many fields, but computing it directly from the definition is often too slow to be practical… Webproductivity in diminishing yield harmonic segments.
