Abstract

This paper presents maximum entropy power spectrum estimation of a 2-D information signal given that multirate low-resolution observations are available. Since the exact calculation of the 2-D maximum entropy power spectrum is not practical, we propose an efficient method utilizing slices in the 2-D discrete Fourier transform (DFT) domain and the duality in convex programming. We investigate the properties of our solution and provide numerical examples to demonstrate the performance of the new method.
