Multichannel 2-D AR spectrum estimation
Charles W. Therrien, H.T. El-Shaer · IEEE Transactions on Acoustics Speech and Signal Processing · 1989
Spectral estimation for multiple 2-D signals by autoregressive modeling is discussed. The procedure computes the entire spectral matrix of autospectra and cross spectra for the set of 2-D signals. Specific differences between AR models for this problem and those for lower dimensional problems are discussed. Experimental results are presented.
