... m) ≥ 0andB(k, m) ≥ 0, and their values depend on k and m. For example, according to Figure 7, for the first case when the summation is within the range of I 1 , A(k, m)=0andB(k, m) >0; and hence, ... multipath fading channels for comparison. Since the estimator [14] generally has a better perfor- mance than the estimators [5,12,14] in multipath channels, for clarity, only the...
