Multitaper

Comparison of periodogram (black) and multitaper estimate (red) of a single trial local field potential measurement. This estimate used 9 tapers.

In signal processing, multitaper analysis is a spectral density estimation technique developed by David J. Thomson.[1] [2] 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.
