Title: | Non-Iterative DOA estimation using discrete fourier transform interpolation | Authors: | Chen, Y Ko, AHC Tam, WS Kok, CW So, HC |
Issue Date: | 2019 | Source: | IEEE access, 2019, , v. 7, p. 55620-55630 | Abstract: | A fast and accurate non-iterative direction-of-arrival (DOA) estimation algorithm for multiple targets in additive white Gaussian noise is devised in this paper. The proposed estimator makes use of the two highest magnitudes discrete Fourier transform (DFT) coefficients of the input data and two of their associated neighboring bins, resulting in a deterministic complexity of O(N (1 + log(N))) with N being the number of sensors. The bias and mean squares error of the DOA estimates are analyzed. The simulation results are presented to validate the correctness of theoretical derivation and demonstrate the superiority of the devised estimator over several conventional DOA estimators. | Keywords: | Direction-of-arrival Single snapshot Interpolation Discrete fourier transform |
