A Variational Technique for Source Localization Based on .. - Cetin, Malioutov.. (2002) (Correct)
....problem is that of direction of arrival (DOA) estimation, which we focus on in this paper. Conventional beamformers for DOA estimation have a limited resolution, and this has led to the development and successful application of more advanced techniques. Examples are Capon s minimum variance method [1], and a variety of superresolution methods based on eigenvalue decomposition, such as MUSIC [2] Such methods exploit the presence of a small number of sources in order to focus the estimated signal energy towards the source DOAs to achieve superresolution. We propose a different perspective for ....

Robust Minimum Variance Beamforming - Lorenz, Boyd (Correct)
....signal covariance derived from the sample covariance of recently received samples of the array output, e.g. Ryc y(k)y(k) c c nXn. k The minimum variance beamformer (MVB) is chosen as the optimal solution of minimize w Rvw subject to w a(O) 1. This is commonly referred to as Capon s method [1]. Equation (3) has an analytical solution given by Wmv Equation (3) also differs from (2) in that the power expression we are minimizing includes the effect of the desired signal plus noise. The constraint w a(O) 1 in (3) prevents the gain in the direction of the signal from being reduced. A ....

Robust Adaptive Beamforming Using Data Dependent Constraints - Bell, al. (1997) (Correct)
....a wider main beam which is robust to D0A uncertainty. 1. INTRODUCTION Adaptive beamfoming is a method for estimating a desired signal impinging on an array of sensors. When the direction of arrival (DOA) of the source is known, the mini mum variance distortionless response (MVDR) beamformer [1] provides a distortionless version of the signal while suppressing noise and interference. However, if there is a mis match between the source DOA and the look direction of the beamformer, there can be significant degradation in per formance, particularly at high signal to noise ratio (SNR) ....

....is an iterative algorithm that requires a sequence of eigendecompositions of intermediate covariance matrix estimates, and therefore, it is still computationally inefficient. A new covariance estimator was recently introduced in [9] by Fourier inverting the Capon power spectral density estimates [13]. Although the Capon covariance estimator was derived primarily for covariance sequence estimation, structured covariance matrices can be readily constructed from covariance sequence estimates. Although the Capon covariance sequence estimator usually gives lower mean squared errors (MSE s) than ....

Amplitude Estimation of Sinusoidal Signals: Survey, - New Results And (Correct)
....Section III several ways to estimate the aforementioned covariance matrix that lead to different WLS amplitude estimators. Additionally, we show that if the restriction of estimating one amplitude at a time is again imposed, we obtain two WLS amplitude estimators that are equivalent to the Capon [2], 3] and amplitude and phase estimation (APES) 4] methods extensively used for spectral analysis. The observation that some general spectral estimators, such as Capon and APES, can be used to solve the problem posed in (1) motivated us to seek other relatively sophisticated spectral analysis ....

A recent study has suggested the choice of matched filters, which gave rise to the matched filterbank (MAFI) approach 1053 587X 00 10.00 2000 IEEE to spectral estimation [6] Even though neither Capon nor APES was derived in the MAFI framework (see [2] and [4] for their original derivations) it was found that both are members of the MAFI approach [6] In the light of the work of [6] we derive in Section IV a generalized MAFI approach to amplitude estimation. Interestingly enough, we show that under certain circumstances, MAFI amplitude ....

Efficient Implementation Of The 2-D Capon Spectral Estimator - Jakobsson, Marple, Jr. Self-citation (Capon) (Correct)
....section, we will briefly review the well known 2 D Capon spectral estimation method and formulate the problem of interest. The Capon spectral estimator was, unlike many other spectral estimation techniques, originally proposed directly in a multi dimensional setting as an arrayprocessing technique [21]. It is a non parametric adaptive matched filterbank approach [22] and follows two main steps: a) Pass the data through a 2 D bandpass filter with varying center frequencies ( 1 ; 2 ) and b) estimate the power at ( 1 ; 2 ) for all 1 2 [0; 2 ) 2 2 [0; 2 ) of interest from the filtered ....
