Configurations of time points (top) and frequency components (bottom) designed for the Block-FFT. Both tables contain 2q rows and p columns. i1 and k1 are row indices and i2 and k2 are column indices for the time and frequency component table, respectively. Time points in rows q+1 to 2q−1 (shaded) are zero due to zero padding. The frequency components in shaded rows q+1 to 2q−1 can be determined by complex conjugation of real signal FT.
