smoothing and MEM spectral analysis
Sergios Theodoridis, N. Kalouptsidis, D. Bakirtzis · 1988
Highly parallel algorithms are derived for multichannel FIR smoothing and MEM spectral analysis. The derived algorithms require O(p) computing time and can be performed on a linear array of O(p) processors, 9 being the order of the filter or AH model. I'hus a computational saving of one order of magnitude is achieved compared to Levinson type algorithms.
