Assessing the performance of compound smoother in extracting sine signal from heavy noise
The 4253H (Twice) is a type of established non-linear compound smoother that has the capability to extract signal from heavy noise. In this paper, the performance of 4253H (Twice) in recovering the sine signal with the existence of four different percentage of contaminated error were assessed. The p...

| Summary: | The 4253H (Twice) is a type of established non-linear compound smoother that has the capability to extract signal from heavy noise. In this paper, the performance of 4253H (Twice) in recovering the sine signal with the existence of four different percentage of contaminated error were assessed. The performances are measured by the mean of least square coefficient linear regression of the smoothed sequence on the signal sequence and Estimated Integrated Mean Square Error via simulation process. The 4253H (Twice) performs best in extracting the signal at low frequency. At the present of 75% contaminated error, this method manages to recover the signal fairly well. Therefore, 4253H (Twice) is an effective method in smoothing the heavy noise data. |
