Hi, I am trying to get forward/backward predictor coefficients from the ladder relection coefficients using the following recursion. (From haykins book) a_m(n) = [a_{m-1}(n) 0] + k_{f, m} [0 c_{m-1}(n-1)] --------- (1) c_m(n) = [0 c_{m-1}(n-1) + k_{b, m} [a_{m-1}(n) 0] --------- (2) where a_m and c_m correspond to forward/backward predictor coefficients in this manner. a_m = [1 -w_...

Hello experties, I have the following System in the time domaine that I want to solve with the unknown x1 and x2: y1 = h11*x1 + h21*x2 (1) 0...

Hello experties, I have the following System in the time domaine that I want to solve with the unknown x1 and x2: y1 = h11*x1 + h21*x2 (1) 0 = h12*x1 + h22*x2 (2) with: h11, h21, h12, h22 are the room impulse responses. I found the following solution: x1 = [(h11-h21(h22^-1)h12)^-1]*y1 x2 = -(h22^-1)*h12*x1 I calculated the impulse inverses with the Levinson-Darvin algorithm. The Prob...
