29. The variance of multitaper spectrum estimates for real Gaussian processes

Author

Walden, A.T., McCoy, E., and Percival, D.B.

Subjects
Gaussian processes -- Research, Spectrum analysis -- Research, Business, Computers, Electronics, Electronics and electrical industries
Abstract

Studies of multitaper spectral estimation reveal that at near zero or Nyquist frequency, the approximation is inadequate even for white noise. The variance expression is obtained for a stationary real-valued time series. The multitaper variance expression for real-valued processes cannot be obtained as a special case for circular symmetric processes.
