SNR improvement based on piecewise linear interpolation

Pengfei Xu – Yinjie Jia

   Interpolation improves the resolution of the curve. Based on the stationary characteristics of the signal and the non- stationary characteristics of the noise, the theoretical proof indicates that the piecewise linear interpolation can improve the signal- to-noise ratio, which is further confirmed by simulation results.

Keywords: signal-to-noise ratio improvement, piecewise linear interpolation, signal enhancement
