Filtering Decompositions with Respect to Adaptive Test Vectors
نویسنده
چکیده
The adaptive ltering decompositions are based on the tangential frequency ltering decompositions (TFFD). During the iteration with a preliminary preconditioner, the adaptive test vector method calculates new test vectors for additional TFFDs. The adaptive test vector iterative method allows the combination of the tangential frequency decomposition and other iterative methods such as multi-grid. The connection with the TFFD improves the robustness of these iterative methods with respect to varying coeecients. Realistic numerical experiments connrm the eeciency of the presented algorithms.

Adaptive Filtering
In this paper, the adaptive ltering method is introduced and analysed. This method leads to robust algorithms for the solution of systems of linear equations which arise from the discreti-sation of partial diierential equations with strongly varying coeecients. These iterative algorithms are based on the tangential frequency ltering decompositions (TFFD). During the iteration with a preliminary...

This paper presents new adaptive filtering techniques used in speech enhancement system. Adaptive filtering schemes are subjected to different trade-offs regarding their steady-state misadjustment, speed of convergence, and tracking performance. Fractional Least-Mean-Square (FLMS) is a new adaptive algorithm which has better performance than the conventional LMS algorithm. Normalization of LMS ...
متن کاملAdaptive Information Filtering: improvement of the matching technique and derivation of the evolutionary algorithm
Adaptive Information Filtering is concerned with ltering information streams in changing environments. The changes may occur both on the transmission side (the nature of the streams can change) and on the reception side (the interests of a user can change). The research described in this report details the progress made in a prototype Adaptive Information Filtering system based on weighted trig...
متن کاملAn Adaptive Hierarchical Method Based on Wavelet and Adaptive Filtering for MRI Denoising
MRI is one of the most powerful techniques to study the internal structure of the body. MRI image quality is affected by various noises. Noises in MRI are usually thermal and mainly due to the motion of charged particles in the coil. Noise in MRI images also cause a limitation in the study of visual images as well as computer analysis of the images. In this paper, first, it is proved that proba...
