Application of shifted band-limited multiple fourier linear combiner in pre-estimation and filtering of human tremor

Background: To suppress the human tremor, researchers all over the world devote themselves to develop a wearable tremor-suppression orthosis. Objective: To introduce and modify commonly used Fourier linear combiner and a series of derived algorithms. Methods: The weighted Fourier linear combiner was introduced into a new algorithm, shifted bandlimited multiple Fourier linear combiner. Iterative process could change as the object changed. A certain bandwidth constraint was set to ensure the filtering properties of the algorithm, limiting the bandwidth range. Results And Conclusion: The shifted bandlimited multiple Fourier linear combiner is more adaptive and accurate for the tremor filtering and estimation.
