Abstract
This paper presents an accurate algorithm for frequency estimation, which uses both the amplitude and phase of the DFT( Discrete Fourier Transform) results. The theory analyzes show that the algorithm is an unbiased estimator. The simulation results show that the performance of the algorithm is close to MCRB ( Modified Cramer-Rao Lower Bound) , and the characterization of SNR ( Signal Noise Ratio) threshold of the algorithm is similar to the maximum likelihood frequency estimation algorithm. The algorithm is easy to implement with hardware as the analyses of complicity implied.关键词
