... satisfies (21) and, therefore, is op- timal only for LS and SLS estimators and/ or for the un- correlated channel case (r = 0). From this figure, we ob- serve that the difference in performance between ... investigated for each of these techniques and their channel estimation performances are analyzed. In the case of multiple LS channel estimates, the best linear unbiased es...
