Abstract :
A computationally efficient procedure for the reconstruction of the impulse response of a (minimum- or nonminimum-phase) linear time-invariant system from its bispectrum is presented. This method is based on computing cepstrum of the impulse response sequence from the ω1=ω2 slice of the bispectrum. The algorithm can be implemented by using only the one-dimensional fast Fourier transform algorithm
