Abstract:

Discusses the 2-D minimum free energy (MFE) parameter and spectral estimation method and presents an algorithm for its implementation. Notes a profound lack of results in the literature on 2-D spectral estimation methods and on their comparison. To address this issue and to impart an overall impression of the performance of 2-D MFE, compares results from the Levinson method, a maximum entropy method (MEM), and a hybrid method with 2-D MFE. Points out that 2-D MFE can provide superior spectral estimates to that produced with MEM and that, in general, MFE requires a larger area of correlation support than the hybrid method. Also notes that 2-D MFE can provide superior spectral estimation over the 2-D Levinson algorithm.
