چکیده

Set-membership algorithms, including the conventional optimal bounding ellipsoid (OBE) algorithm, require a priori knowledge of exact error bounds which is unknown in most applications. Conservative (over-estimated) error bounds used in practice lead to inconsistent parameter estimation. The novel OBE algorithm with automatic bound estimation (OBE-ABE) is shown to be consistently convergent without a priori knowledge of error bounds, even in correlated-error environments. Computationally e cient variants of this algorithm for both time-invariant and time-varying systems are presented. Simulations are performed to demonstrate the merit of the algorithms.

Automatic Bounding Estimation in Modified Nlms Algorithm

Modified Normalized Least Mean Square (MNLMS) algorithm, which is a sign form of NLMS based on set-membership (SM) theory in the class of optimal bounding ellipsoid (OBE) algorithms, requires a priori knowledge of error bounds that is unknown in most applications. In a special but popular case of measurement noise, a simple algorithm has been proposed. With some simulation examples the performa...

Research of Blind Signals Separation with Genetic Algorithm and Particle Swarm Optimization Based on Mutual Information

Blind source separation technique separates mixed signals blindly without any information on the mixing system. In this paper, we have used two evolutionary algorithms, namely, genetic algorithm and particle swarm optimization for blind source separation. In these techniques a novel fitness function that is based on the mutual information and high order statistics is proposed. In order to evalu...

Performance Studies on a \ Quasi - OBE " Algorithm for Real - time

|A novel algorithm is studied for the iden-tiication of linear-in-parameters models. This technique is dubbed \Quasi-OBE" (QOBE) because it is based on the principles of optimal bounding ellip-soid (OBE) identiication, but has other geometric and classic least-squares interpretations that enhance its interpretability and application potential. Convergence behavior of both the central point esti...

A Novel Blind Watermarking of ECG Signals on Medical Images Using EZW Algorithm

Introduction:In this study, ECG signals have been embedded into medical images to create a novel blind watermarking method. The embedding is done when the original image is compressed using the EZW algorithm. The extraction process is performed at the decompression time of the watermarked image. Materials and Methods: The multi-resolution watermarking with a secret key algorithm developed in th...
