IMPROVING CONVERGENCE OF SINE FITTING ALGORITHMS

M. Fonseca da Silva, A. Cruz Serra

Abstract

Signal-processing applications frequently use least-square sine fitting algorithms. The parameter estimation provided by these algorithms is exposed to errors due to different causes. Good results in sinewave estimation may be achieved when the frequency is unknown by applying the new method presented in this paper.
