WebMar 1, 2024 · In this brief, we propose a new receding horizon finite impulse response (FIR) filter that minimizes the weighted Frobenius norm with embedded unbiasedness in discrete-time state-space. The filter, called the discrete-time weighted Frobenius norm unbiased FIR (DTWFNUF) filter, belongs to a class of maximum likelihood estimators. … WebFrobenius norm and its monotonicity. Given A∈Rm×n, let ∥A∥F = i=1∑m j=1∑n aij2 known as the Frobenius norm. Further, let A,B F = trace(A⊤B), with A,B ∈ Rm×n known as the Frobenius inner product. (a) (2 points). Prove that ∥⋅∥F is a norm in Rm×n. Hint: You may use the fact that the usual Euclidean norm ∥(x1,…,xn)∥2 = x12 +…+xn2 is indeed a norm.
