ABSTRACT This project presents a novel voice verification system using wavelet transforms. The conventional signal processing techniques assume the signal to be stationary and are ineffective in recognizing non stationary…
ECG signal denoising and baseline wander correction based on the empirical Mode decomposition
Abstract : The electrocardiogram (ECG) is widely used for diagnosis of heart diseases. Good quality ECG are utilized by physicians for interpretation and identification of physiological and pathological phenomena. However,…
Adaptive DS-CDMA Receiver with Code Tracking in Phase Unknown Environments
In this paper, we propose and analyze a new non coherent receiver with PN code tracking for direct sequence code division multiple access (DS-CDMA) communication systems in multipath channels. We…
An Edge Guided Image Interpolation Algorithm via Directional Filtering and Data Fusion
Abstract: Preserving edge structures is a challenge to image interpolation algorithms that reconstruct a high resolution image from a low resolution counterpart. We propose a new edge-guided non-linear interpolation technique…
PAPR ANALYSIS OF DHT-PRE CODED OFDM SYSTEM FOR M-QAM
ABSTRACT : High Peak to Average Power Ratio (PAPR) is one of the major drawbacks in Orthogonal Frequency Division Multiplexing (OFDM). The High PAPR increases the complexity of Analogue to…
Compress Compound Images in H.264/MPEG-4 AVC by Fully Exploiting Spatial Correlation
ABSTRACT : Compound images consist of text, graphics and natural images, which present strong anisotropic features. It makes existing image coding standards inefficient on compressing them. To solve the problem,…
Adaptive Active Constellation Extension Algorithm for Peak-to-Average Ratio Reduction in OFDM
Abstract: For PAR reduction in OFDM systems, the clippingbased Active Constellation Extension (ACE) technique is simple and attractive for practical implementation. However, we observe it cannot achieve the minimum PAR…
Fast Sparse Image Reconstruction Using Adaptive Nonlinear Filtering
Abstract : Compressed sensing is a new paradigm for signal recovery and sampling. It states that a relatively small number of linear measurements of a sparse signal can contain most…
A REAL TIME NUMBER PLATE RECOGNITION
ABSTRACT Automatic Number Plate Recognition (ANPR) is a real time embedded system which identifies the characters directly from the image of the license plate. It is an active area of…
Stationary and Non-Stationary noise removal from Cardiac Signals using a Constrained Stability Least Mean Square Algorithm
Abstract : Adaptive filter is a primary method to filter ECG signal, because it does not need the signal statistical characteristics. In this paper we present a novel adaptive filter…
