Robust multichannel subspace identification
L. Hoteit · Electronics Letters · 1999
The non-robustness to channel order overestimation and lack of disparity of the Moulines subspace (SS) and the Tong least-squares (LS) approaches are considered to be major limitations to their use in practical situations. A remedial technique is proposed that can be applied to both approaches, offering them the robustness they lack.
