Pulse Signal Interference Detection Algorithm Based on Data Mining
The acquisition process of the pulse signal is easy to be influenced by the environment, thus the pulse signal interference.In other words, the pulse signal is polluted by the environment noise.In order to objectively describe the signal polluted degree, this paper proposes a piecewise linear representation of time series of the pulse signal based on the interference detection algorithm, and establishes the pulse template, the template signal and actual sampling signal between the matching degree (i.e.fitting error), resulting in an objective expression of human pulse contains interference section level (i.e., signal quality) algorithm.
