Wiener filtering 6.011, Spring 2018 Lec 20 1
Unconstrained Wiener filter structure - m x m y y [ n ] x [ n ] + + h [·] 2
Unconstrained Wiener filter solution - m x m y D yx ( e j Æ ) H ( e j Æ ) = x [ n ] y [ n ] + + D xx ( e j Æ ) 3
Compared with static LMMSE estimator - m x m y D yx ( e j Æ ) H ( e j Æ ) = x [ n ] y [ n ] + + D xx ( e j Æ ) - m X m Y T c X Y ( C XX ) - 1 + + X Y 4
