Fig. 1From: An MDCT domain three-point interpolation-based low-complexity frequency estimatorMSE comparison of the estimators for single-tone sinusoidal input without noise. Two sets of the sinusoidal signal were used. The results of the two sets are presented in (a) and (b). We set l 0 = 46 for (a) and l 0 = 510 for (b). There were averages of 10,000 runs for each frequency setBack to article page
