Let I" I`' denote a pair of uncorrelated , zero - mean | 2* I | random vectors having covariance matrix 1 7 . LetZ = GF + W!where6 = [ 1 1 ]( a ) Determine the LMMISE estimate !" of I' given I as well as the associated mean - square EllumI bj State the orthogonality principle as it applies in this setting*
