Abstract :
Through a series of simulations with one dimensional real digital signals, the effects of various degrees of phase degradation for different lengths of sequences and for different choices in the set of sampling frequencies on the quality (as measured by normalised mean-square-error-NMSE) of signals reconstructed from noisy Fourier transform (FT) phases is established.
