Estimation of Cross-Spectra via Overlapped Fast Fourier Transform Processing
Abstract
The optimum overlap to be used for estimation of cross-spectra via FFT processing of windowed data is shown to be identical to that for estimation of auto-spectra. In addition, a useful geometric interpretation of the random errors in cross-spectral estimation, and their covariances, is furnished.
