the EM algorithm to provide a more accurate description of the difference-image statistics. We define this estimation procedure as an adaptive semiparametric approach. On the one hand, the term “adaptive” points out the fact that the proposed method does not assume any a priori model on the data distribution; this. constraints , . Frequency estimation and model order selection are two important topics in line spectral estimation. Given f k’s and K, s k’s can be obtained by a simple least-squares method according to (1). This paper is mainly focused on frequency estimation but we also incorporate existing model order selection tools in our methods.

The adaptive thresholding estimators are easy to implement. The numerical performance of the estimators is studied using both simulated and real Size: KB. Any feedback from readers is welcome.

A multichannel characterization for autoregressive moving average (ARMA) spectrum estimation in subbands is considered in this article.
The fullband ARMA spectrum estimation can be realized in two-channels as a special form of this characterization. A complete orthogonalization of input multichannel data is accomplished using a modified form of Cited by: 6. COURSE SYLLABUS: EE - ADAPTIVE SIGNAL PROCESSING.

An indirect adaptive control algorithm for a MIMO plant is studied. It is shown that Polyak - Ruppert estimation algorithm along with the simple dead-beat control law constitutes an adaptive control strategy that achieves the highest possible rate of convergence for the quadratic criterion.
This paper deals with the problem of two-dimensional autoregressive (AR) estimation from noisy observations. The Yule-Walker equations are solved using adaptive steepest descent (SD) algorithm. Performance comparisons are made with other existing methods to demonstrate merits of the proposed by: 1.
Linear prediction based adaptive algorithm for a complex sinusoidal frequency estimation Article in AEU - International Journal of Electronics and Communications 67(6)– June with. "Adaptive Filters" by C.F.N. COWAN and P.M. GRANT. filter realization is devoted to full digital as well as to CCD realizations of adaptive FIR filters based on the LMS algorithm.

In passive sonar, adaptive algorithms can be used to cancel strong sinusoidal self-interferences. In order to correctly recover low-power target signals during the early stages of processing, these adaptive algorithms must provide fast convergence and, at the same time, narrow notches at the frequencies of the sinusoids.
In this respect, the gradient adaptive lattice Cited by: 3. The second adaptive estimation algorithm resulted from considering the best adaptive estimate to be the mode of the a posteriori probability density of the state trajectory and unknown covariance matrices, conditioned on all the avail able measurements.
The primary contribution is the algorithm used to solve for the conditional mode. Abstract. A novel adaptive algorithm of IIR lattice notch filter realized by all-pass filter is presented.
The time-averaged estimation of cross correlation of the present instantaneous input signal and the past output signal is used to update the step-size, leading to a considerably improved convergence rate in a low SNR situation and reduced steady-state bias and by: 2.

Later, the two-multiplier lattice structure is presented along with a new technique for. current frequency estimation algorithm -. But the algorithm is more sensitive to the initial parameter value, and it is difficult to balance the convergence rate and the long tracking precision.
To resolve the above problems, a novel adaptive frequency estimation algorithm based on interpolation FFT and improved ANF is proposed.
