Let Y1, Y2, Y3, be a sequence of independent non- identical random variables with mean E[Yi]=0, and Var(Yi)= ₁. For deterministic variables cwe define the discrete- time random process as X(n)= c₁Y1+c₂Y2 ... +cYn, n=1, 2,3,..., N .... Now, we define a column vector X=[X(1), X(2), X(N)]^T Find the mean vector mx, correlation matrix Rx, and covariance matrix Cx for random vector X ....
