Combining Co-operative Diversity in Wireless Communication
Abstract: Wireless devices cannot employ Multiple Input Multiple Output (MIMO) due to hardware or size limitation. Wireless device should replicate their single antenna virtually to act like MIMO system for better performance. This process is possible through a new system known as co-operative communication. In this system, the terminal or nodes combined to transmit the signals to follow an antenna array and form the diversity. Diversity is nothing but transfer of …

Interactive Projector: Application of MATLAB Embedded JAVA
Abstract: In this paper, the authors have worked on a technique to convert a simple projector into an interactive projector by using a LASER pointer. For this, the authors specially concentrated on transformation, namely projective transformation, for calibration purpose, feature extraction of a color image for locating a pointer and java commands to perform mouse operations. The authors manipulated an interested part of a captured image and matched its coordinates with …

Performance Analysis of Speech Performance Analysis of Speech Recognition using Advanced Algorithm
Abstract: In this paper, the authors have worked on a speech processing technique wherein they took audio speech as input signal from user and by recognition process, they perceived recorded word. Specifically, the authors concentrated on the amplitude and zero cross of speech signal, and two of the most important and useful terms, namely MFCC and Mahalanobis distance, for the purpose of getting an efficient outcome. The authors evaluated the proposed …

Wearable Computer Vision based Human Assistance System using Android 4.0.3 ICS Operating System
Abstract: This paper describes a well defined and improved system for the human assistance, based on wearable computer vision using Android ICS operating system. The information is traditionally confined to paper or digitally to a screen; in contrast the proposed system introduces an Android tablet based wearable gestural interface to attempt for bringing information out into the tangible world. The system provides an extension to existing gesture interface system by integrating …

Empirical Mode Decomposition versus Wavelet filtering for Time Domain Electromagnetic Signals
Abstract: Time Domain Electromagnetic (TDEM) methods are used for exploration of deep seated mineral deposits by measuring sub-surface conductivity of the earth. The response of earth is measured by an induction coil. The signals acquired are contaminated by variety of noises. Signal filtering plays a major role in order to obtain deeper information regarding subsurface conductivities. Various methods based on conventional DSP filters, wavelets, etc. have been attempted. This paper explains …
