Subspace Methods
摘要
Subspace methods [1, 2, 5–9] are a widely used technique for overcoming the limitations of TDOA methods. Historically, Kumaresan [3], Barabell [4], Kailath [5], and Cadzow have provided crucial insights [10–12] into the role of subspace techniquesSubspace techniques in direction-of-arrival (DOA) estimation. Bhaskar Rao [13] offers an excellent description of these methods, as does Paulraj in his review article [5, 14].
