| Abstract: | Models of frequency estimation and DOA (Direction-of-arrival) estimation are defined respectively. Wavelet packet-based frequency estimation is introduced. Equivalence of frequency and DOA estimation, and relationships of resolution between them are investigated. Consistency of them is validated by the simulation results. |
| Keywords: | signal model wavelet packet frequency estimation DOA. |
