Foregasting with Abaptive Filtering

— During the past decade Régression Analysis has gained wide acceptance as a method for preparing medium and long range forecasts for time series. However/for a shortterm forecasting situation or when the number of observations is small, régression analysis is costly and of ten impractical. Exponential smoothing is the forecasting method most of ten used in these latter situations, but it has s...

Adaptive Filtering with Averaging

Adaptive ltering algorithms are considered in this work. The main e ort is devoted to improve the performance of such algorithms. Two classes of algorithms are given. The rst one uses averaging in the approximation sequence obtained via slowly varying gains, and the second one utilizes averages in both the approximation sequence and the observed signals. Asymptotic properties{convergence and ra...

Speech Enhancement by Modified Convex Combination of Fractional Adaptive Filtering

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 ...

An 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...

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...
