Recursive Multichannel Maximum Entropy Spectral Estimation
Martin E. Morf, A. Vieira, Daniel T. L. Lee, T. Kailath · IEEE transactions on geoscience electronics · 1978
We present a generalization to the multichannel case of the well-known Burg maximum entropy technique for spectral estimation. The extension is obtained by first obtaining the proper generalization of the scalar reflection coefficients to the multichannel (or matrix) case.
