Two new weighted-least-squares algorithms for magnitude-spectrum estimation from the bispectrum are presented. The performance of these algorithms is compared both with direct-magnitude-spectrum estimation and with several previously proposed algorithms for magnitude-spectrum estimation from the bispectrum. It is shown that the new algorithms result in more accurate magnitude-spectrum estimates than these other approaches.
