| Abstract(in English) | The adaptive frequency estimation has many engineering applications, and a lot of techniques of the estimation have been worked out. In this paper, we propose a new computationally efficient adaptive frequency estimation algorithm which is based on the blocked variable sampling and the synchronous addition /subtraction processing (SAS). The SAS method requires additions and subtractions only, which makes the new frequency estimation technique very attractive in terms of computation load. It is showed that the quadratic function approximation is effective to detect the peak of accumulated values being necessary for the frequency estimation, and also we consider the high speed frequency estimation by the Overdetermined-NFT. Extensive simulations are presented to reveal the performance of the proposed method, and it becomes clear that the proposed method can estimate the input frequency accurately, and the computation load is very low. |
