摘要：

Pulsar signal is a typical non-stationary signal that has a minimum signal to noise ratio and vast outliers which will direct affect the observation accuracy of pulsar signal time of arrival (TOA), reduce the precision of the filter and make the filter loss of stability. In this paper, outliers are eliminated based on wavelet by set adaptive soft threshold in detailed components. The simulation results demonstrate the accuracy of pulsar signal TOA improves significantly after outliers eliminated by adaptive soft threshold.
