| 英文摘要 | In this letter, we propose shrinkage-based capon (s-capon) and apes (s-apes) spectral estimators by minimizing the mean-square error (mse) of standard capon and apes in a linear regression framework. the proposed methods are shown to give more accurate spectral estimates but lower resolution than the methods they based on. we combine capon with the proposed s-capon and s-apes to overcome the resolution limit of shrinkage-based methods for estimation of both frequency and amplitude of spectral lines. the so-obtained capon-scapon and capon-sapes spectral estimators, which have about the same computational complexity as capon, are compared with the capon-apes (capes) by numerical examples. simulations show that the capon-scapon performs similarly to capes in a wide range of signal-to-noise ratio, and the capon-sapes always gives more accurate spectral amplitude (less bias and lower mse) than capes. |
