Subspace-based frequency estimation utilizing prior information
2011 (English)In: 2011 IEEE Statistical Signal Processing Workshop (SSP), IEEE , 2011, 533-536 p.Conference paper (Refereed)
In certain frequency estimation applications one or more of the underlyingfrequencies are known. For example, in rotary machines the known frequencymay be a strong network frequency masking important closely spacedfrequencies. Being able to include this information in the design of the estimator can be expected to improve the performance when estimating such closely spaced frequencies. We present a framework to include such priorinformation in a class of subspace-based estimators. Through Monte Carlo simulations and real-data applications we show the usefulness of our approach.
