摘要
Abstract
The fourth order mixed cumulants (FOMC) of damped exponential model is derived, which contains an accurate damped frequency,damped factor and other information. A method of parameter estimation using state space model based on the fourth order cumulant is proposed,which can achieve the joint estimation of damped frequency and damped factor at low computation complexity. The simulation results show that the method can effectively restrain Gaussian color noise ,with superior performance.关键词
