What is a multitaper method?
In signal processing, multitaper is a spectral density estimation technique developed by David J. Thomson. It can estimate the power spectrum SX of a stationary ergodic finite-variance random process X, given a finite contiguous realization of X as data.
What is a multitaper spectrogram?
The multitaper method works by averaging together multiple independent spectra estimated from a single segment of data. The innovation of the multitaper method is that, instead of using a single-taper function to compute the spectrum, it uses multiple taper functions called discrete prolate spheroidal sequences (DPSS).
