Performance analysis for fast frequency estimation with short sequences
Ting Shu, LU Jin-hui · Systems engineering and electronics · 2006
The performances of the three computationally efficient frequency estimation algorithms with short sequences are discussed in detail.First,the principle of frequency estimation is presented.Further,the Cramer-Rao bound of frequency estimation and the performance analysis based on the simulation results and measured data results are derived.The performances are compared with those of other frequency estimation algorithms.The explanation for the SNR threshold is also provided.Some general conclusions are significant and valuable to engineers in practical designing.
