When a signal is either known to be of minimum phase or the analysis requiring phase information can accept the phase estimated by regarding the signal as a minimum phase signal, a simple method presented here can calculate the phase easily from the power spectrum. If a signal is a decaying signal approaching zero, the signal can be extended to its double length by padding zeros. The zero-padded portion of such double length data can be taken as a result of cancellation between two double length odd and even signals. Symmetry and anti-symmetry associated with the DFT of even data and odd data makes the recovery of the phase possible. Methods of deconvolution to reconstruct the original spectrum from the spectrum of the zero padded double length data is also discussed. Phase recovery not restricted to the minimum phase depends on the bispectrum, which is the Fourier transform of the third order cummulant. An algorithm that estimates phase from the bispectrum was studied for its robustness and efficiency and compared with the phase estimation directly from the power spectrum. <\/jats:p>","DOI":"10.1142\/s021812669700019x","type":"journal-article","created":{"date-parts":[[2003,10,15]],"date-time":"2003-10-15T20:35:19Z","timestamp":1066250119000},"page":"261-272","source":"Crossref","is-referenced-by-count":0,"title":["Recovery of Phase Using Power Spectrum and Bispectrum"],"prefix":"10.1142","volume":"07","author":[{"given":"Kunio","family":"Takaya","sequence":"first","affiliation":[{"name":"Electrical Engineering, University of Saskatchewan, 57 Campus Drive, Saskatoon, Saskatchewan, S7N 5A9, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"container-title":["Journal of Circuits, Systems and Computers"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S021812669700019X","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,6]],"date-time":"2019-08-06T23:46:57Z","timestamp":1565135217000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S021812669700019X"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1997,8]]},"references-count":0,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2011,11,21]]},"published-print":{"date-parts":[[1997,8]]}},"alternative-id":["10.1142\/S021812669700019X"],"URL":"https:\/\/doi.org\/10.1142\/s021812669700019x","relation":{},"ISSN":["0218-1266","1793-6454"],"issn-type":[{"value":"0218-1266","type":"print"},{"value":"1793-6454","type":"electronic"}],"subject":[],"published":{"date-parts":[[1997,8]]}}}
