【Abstract】 This paper presents a new method of estimating numbers and frequencies for sinusoid signals based on TransDimensional Simulated Annealing(TDSA) algorithm. This paper introduces penalty term and least square into TDSA, and gives a method that simultaneously estimates the numbers and frequencies of sinusoids signals in white gaussian noise. Finally, the validity of this method is well verified by the simulation.更多还原
