Efficient Time Recursive Coherence Spectrum Estimation
(2012) 20th European Signal Processing Conference, 2012 p.425-429- Abstract
- The coherence spectrum is of notable interest as a bivariate
spectral measure in a variety of application, and the topic has
lately attracted notable interest with the recent formulation
of several high-resolution data adaptive estimators. In this
work, we present computationally efficient time recursive
implementations of the recent iterative adaptive approach (IAA)
estimator, examining both the case of complete data sets and
when some observations are missing. The algorithms continues the recent development of exploiting the estimators’ inherently low displacement rank of the necessary products of Toeplitz-like matrices, extending these to time-updating formulations for the...
