Estimation for Transients in the Frequency Domain
提出一种频域方法，用于估计被瞬态信号污染的数据，通过类似复解调的技术分别估计瞬态和噪声参数，并通过模拟实验检验估计性质。
Abstract We consider the frequency domain approach for analyzing data that have been contaminated by transients. After formulating an additive model for transients, we suggest frequency domain estimation procedures. Part of our approach is much like complex demodulation, and this approach enables us to estimate separately the parameters for the transient and noise parts. Some simulation experiments are conducted to examine the properties of our estimates.
