Adaptive On-line Learing Algorithm for Robust Estimation of Parameters of Noisy Sinusoidal Signals

In many applications, very fast methods arc required for estimating of parameters of harmonic signals distorted by noise. Most of the known digital algorithms arc not fully parallel, so that the speed of processing is quite limited. In this paper new parallel algorithms arc proposed, which can be implemented by analogue adaptive circuits employing some neural networks principles. Algorithms bas...

Adaptive HMM filters for signals in noisy fading channels

In this paper, Kalman filtering (KF) and hidden ,Markov model (HMM) signal processing techniques are coupled to demodulate signals transmitted through noisy fading channels. The demodulation scheme presented can be applied to both digital M-ary differential phase shift keyed (MDPSK) and anslog frequency modulated (FM) signals. Adap tive state and parameter estimation algorithms are devised baae...

A New Adaptive Algorithm for the Polygonization of Noisy Imagery

This report introduces a novel adaptive image segmentation algorithm which represents images by polygonal segments and which is particularly suitable for the segmentation of noisy imagery. At first we suggest an intuitive generative model and its associated cost function. The cost function can effectively be optimized by a hierarchical triangulation algorithm, which iteratively refines and reor...

A Convolutional Neural Network based on Adaptive Pooling for Classification of Noisy Images

Convolutional neural network is one of the effective methods for classifying images that performs learning using convolutional, pooling and fully-connected layers. All kinds of noise disrupt the operation of this network. Noise images reduce classification accuracy and increase convolutional neural network training time. Noise is an unwanted signal that destroys the original signal. Noise chang...

Denoising Ecg Signals Using Adaptive Filter Algorithm

120  ABSTRACT One of the main problem in biomedical data processing like electrocardiography is the separation of the wanted signal from noises caused by power line interference, external electromagnetic fields, random body movements and respiration. Different types of digital filters are used to remove signal components from unwanted frequency ranges. It is difficult to apply filters with fix...
