Hi All,
I need your help. Currently, I am so confused about how to solve this equation E[u(n-1)u(n-1)'] and E[u(n-1)u(n)']. Are they equal to autocorrelation and cross correlation matrix? If it is yes, how to implement the cross correlation matrix because I think I can not use toeplitz function like if I do in autocorrelation matrix.
I really thank for your valuable answers or comments.
Regards,
Suci
