Minimum Mean Square Error Estimation Under Gaussian Mixture Statistics
John T. Flam, Saikat Chatterjee, Kimmo Kansanen +1
This paper investigates the minimum mean square error (MMSE) estimation of x, given the observation y = Hx+n, when x and n are independent and Gaussian Mixture (GM) distributed. Th…
