Various Adaptive filtering methods are using to filter Cardiac signals. The two basic adaptive filtering algorithms are LMS (Least Mean Square) and RLS (Recursive Least Square). These Adaptive Algorithms are used to filter artifacts from ECG signal. Adaptive filter minimises the mean square error between the primary input, which is ECG with noise and desired response, which is either ECG or noi...

An adaptive codebook for a onetap pitch filter has been used for determining the pitch filter using an analysis-by-synthesis procedure in CELP coders. In this paper, we first present the formulations for designing an enhanced adaptive codebook for a pseudo-three-tap pitch synthesis filter, which gives a better performance than a conventional one-tap pitch filter. Then, we focus on the stability...

The FPGA (Field-Programmable Gate Array) implementation of an adaptive filter for narrow band interference excision in Global Positioning Systems is described. The algorithm implemented is a delayed LMS (Least Mean Squares) adaptive algorithm improved by incorporating a leakage factor, rounding and constant resetting of the filter weights. This was necessary as the original adaptive algorithm h...

− In this paper a development of an adaptive Kalman filter through a fuzzy inference system (FIS) is outlined. The adaptation is concerned with the imposition of conditions under which the filter measurement noise covariance matrix R or the process noise covariance matrix Q are estimated. The adaptive adjustment is carried out using a FIS based on the whiteness of the filter innovation sequence...

The paper proposed the adapter filter design based on the improved LMS algorithm. The paper first introduced the minimum mean square (LMS) algorithm, which is a very useful and very simple estimated gradient method. This algorithm has been widely used since the early 1960s quickly, its advantage is that the small amount of calculation, and the rapid development of the digital signal processor a...

To separate out the noise behaviour from color image several approaches has been identified, adaptive filter which is extension of LMS filter is one of them to achieve higher signal to noise ratio. In this paper, comparison of adaptive filter with different structure and two dimensional block processing for color image noise abolition is proposed. Simulations for different block size as well as...

In this paper, we proposed a new adaptive median filter for image denoising. In our method, two thresholds have been involved for detecting noises in variable-sized windows. The median filter and the mean filter are combined for changing the value of the corrupted pixels. The filter can preserve the fine details of image while suppressing the impulsive-type noise. The results of the experiments...

This paper describes the program execution framework being developed by the Grid Application Development Software (GrADS) Project. The goal of this framework is to provide good resource allocation for Grid applications and to support adaptive reallocation if performance degrades because of changes in the availability of Grid resources. At the heart of this strategy is the notion of a configurab...

This paper introduces a new parallel algorithm for digital adaptive filters. The algorithm is a look-ahead realization of a transversal filter, where a forgetting factor is employed to diminish the effect of the past errors in the performance index. We have illustrated how such algorithm can be implemented in a regular and modular structure, suitable for VLSI implementation. The maximum samplin...
