摘要：

Based on the interpolated all-phase DFT, a new parameters estimation algorithm for the exponential signal is presented. The proposed algorithm utilizes the all-phase preprocessing unit to construct a new signal sequence by continuously cycle shifting signal samples and summing up N buffered exponential signal sample sequences, and estimate the parameters of the exponential signal based on the interpolated DFT spectrum of the signal sequence generated by all-phase preprocessing. The simulation results verify the effectiveness of the proposed algorithm in terms of estimation accuracy.
