Abstract

Sine signals are used widely in many application. This paper presents a fast signal parameter identification algorithm in terms of the feature parameters of the sine wave with an initial phase. In order to avoid complex calculation and realize fast parameter identification, a multiple three-point identification technique is developed by constructing algebraic equation group based on three discrete observations and solving equations. Moreover, to overcome the difficulty of solving transcendental equations regarding the signal parameters, the original transcendental equation group is transformed into a simple form through a equation transformation. Finally, an example is provided to test the performance of the proposed signal identification method and the simulation results show nice performance.
