is interesting to see that using more training symbols does not improve the performance of the MLE as
expected, because inserting training symbols will reduce the energy ... Furthermore, since the estimation quality of the first stage is available, we use BLUE to obtain
ˆ
θ for exploiting the quality information instead of using the MLE in the M-step as in the standard EM
algorithm.
