Noise Property Real-time Estimation Algorithm Based on Wavelet Transform Domain
摘要
Abstract
In order to address the problems of estimate unknown measurement noise statistical properties(mean and variance)in the case of non-standard Kalman filter, noise property real-time estimation algorithm based on wavelet transform domain is proposed. The presented algorithm can track the changes of the measurement noise and estimate the mean and covariance in real time. Simulation verify the feasibility and effectiveness of the algorithm and the estimation accuracy improved about an order of magnitude estimates of the unknown observation noise variance.关键词
