This function computes the inverse of the 2-dimensional discrete Fourier Transform over any number of axes in an M-dimensional array by means of the Fast Fourier Transform (FFT). In other words, ifft2 (fft2 (a)) == a ... Web14 nov. 2014 · Abstract: Maps of FFT/IFFT stage-dependent minimum bit resolutions against ADC/DAC resolutions and modulation formats are numerically identified and experimentally verified, which ease OOFDM transceiver designs and reduce FPGA logic resource usages without degrading overall transceiver performances.
