The result shows this method working efficiently in signal de-noise, meanwhile, the speed of calculating can be adopted by the remote monitor system of hydro plants.
Therefore, it makes great significance to monitor and manage the hydro-fluctuation -belt of the Three Gorges Reservoir to against the potential eco-problem.
