Abstract:Aiming at the noise signal caused by external environment and sensor reuse in the demodulation system of large capacity fiber grating sensor network, a Threshold Retained Orthogonal Matching Pursuit (TROMP) reconstruction algorithm is proposed based on compressed sensing theory. In this algorithm, the useful signal can be effectively recovered from the noise signal by improving the threshold setting, atom selection and iteration stop condition. Experiments show that: TROMP algorithm can achieve ideal denoising… Show more
