Abstract :
A novel time-domain computation method of the complex cepstrum is proposed. We approximate the complex cepstrum by the solution of a difference equation system and employ a projection method by Gohberg and Feldman (1974) to solve the system. It is proved that under fairly general assumptions the approximations converge to the complex cepstrum. The projection method, together with the proposed time-domain algorithm for the calculation of the linear phase component of a sequence, can also be used as a time-domain deconvolution method
