SBMFLC Algorithm for Pre-estimation and Filtering of Human Tremor

To suppress human tremor, researchers in this field devote themselves to develop a wearable tremor-suppression orthosis, but one of the most important difficulties lies in how to obtain real-time filtering and estimation of the tremor from the input signal. In this article, Fourier Linear Combiner(FLC) and a series of derived algorithms are analyzed first, then an improved algorithm-Shifted Band-limited Multiple Fourier Linear Combiner(SBMFLC) is proposed. Simulation results make it clear that the improved algorithm is more adaptive and accurate to the tremor suppression.
