“…We also consider the fact that scaling of WtCWD ( n ) ( u ; W , , a , b ), by an appropriate scale factor k may further reduce the MRE as it is observed in a few other works reported previously [1,4,6] . In the following, we provide the expression for optimum scale factor ( k opt ) at which the MRE becomes minimum, as well as the scale adjusted optimum MRE value.…”
