Cross-spectrum and coherence function estimation using time-delayed Thomson multitapers

På svenska

Author

Summary, in English

An idea is presented where multitapers are extracted from a known cross-spectrum and applied for estimation of the co- herence function. An important property of the extracted win- dows are the time-delay between left and right tapers. There- fore, time-delayed Thomson multitapers are also proposed as an approximation. Simulations are performed using differ- ent linear filters as well as disturbing white noise and com- parisons are made with the results of the usual Thomson and Welch methods. An example of estimation of EEG coherence is also shown.
