Cooperative Spectrum Sharing Protocol with Selective Relaying System

ABSTRACT In this paper, we propose a two-phase protocol based on cooperative relaying for a secondary system to achieve spectrum access along with a selective relaying primary system. The primary system comprises of a transmitter-receiver pair PT-PR and M relays Ri, i G {1,2,⋯ , M}. The secondary system is a multi-user system with N [...]

Secure communication in the low-SNR regime: A Characterization of the energy-secrecy tradeoff

ABSTRACT             Secrecy capacity of a multiple-antenna wiretap channel is studied in the low signal-to-noise ratio (SNR) regime. Expressions for the first and second derivatives of the secrecy capacity with respect to SNR at SNR = 0 are derived. Transmission strategies required to achieve these derivatives are identified. In particular, it is shown that it [...]

Stereo Vision Images Processing for Real-time Object Distance and Size Measurements

ABSTRACT        Human has the ability to roughly estimate the distance and size of an object because of the stereo vision of human’s eyes. In this project, we proposed to utilize stereo vision system to accurately measure the distance and size (height and width) of object in view. Object size identification is very useful in [...]

HARDWARE ARCHITECTURE FOR VIDEO AUTHENTICATION USING SENSOR PATTERN NOISE

     HARDWARE ARCHITECTURE FOR VIDEO AUTHENTICATION USING SENSOR PATTERN NOISE ABSTRACT Digital camera identification has multiple applications in real-world scenarios. For example, when presenting a video clip as evidence in a court of law, identifying the Source (acquisition device) of the video is as important as the video itself. Not doing so can lead to [...]

SIMPLIFIED MAP DETECTOR FOR BINARY FINGERPRINTING CODE EMBEDDED BY SPREAD SPECTRUM WATERMARKING SCHEME

SIMPLIFIED MAP DETECTOR FOR BINARY FINGERPRINTING CODE EMBEDDED BY SPREAD SPECTRUM WATERMARKING SCHEME ABSTRACT                 In recent years, the distribution of works of art, including pictures, music, video and textual documents, has become easier.  With the widespread and increasing use of the Internet, digital forms of these media are easily accessible. Digital documents Are easy [...]

DESIGN OF GREENHOUSE TEMPERATURE DETECTION SYSTEM BASED ON LINEAR OFFSET INTERFERENC

 DESIGN OF GREENHOUSE TEMPERATURE DETECTION SYSTEM BASED ON LINEAR OFFSET INTERFERENC ABSTRACT           One of the benefits of growing crops in a greenhouse is the ability to control all aspects of the production environment. One of the major factors influencing crop growth is the temperature. Different crop species have different optimum growing temperatures and these [...]

A NOVEL HAND SEGMENTATION METHOD FOR MULTIPLE HAND GESTUR

 A NOVEL HAND SEGMENTATION METHOD FOR MULTIPLE HAND GESTUR ABSTRACT                             Gesture recognition is a topic in computer science and language technoloy with the goal of interpreting human gestures via mathematical algorithms. Gestures can originate from any bodily motion or state but commonly originate from the face or hand. Current focuses in the field include [...]

ARM BASED IMPLEMENTATION OF TEXT-TO-SPEECH (TTS) FOR REAL TIME EMBEDDED SYSTEM

ARM BASED IMPLEMENTATION OF TEXT-TO-SPEECH (TTS) FOR REAL TIME EMBEDDED SYSTEM ABSTRACT                                     An embedded system is a dedicated computer system designed for one or two specific functions. This system is embedded as a part of a complete device system that includes hardware, such as electrical and mechanical components. The embedded system is unlike the [...]

An Efficient Parallel Approach for Sclera Vein Recognition

An Efficient Parallel Approach for Sclera Vein Recognition ABSTRACT Sclera vein recognition is shown to be a promising method for human identification. However, its matching speed is slow, which could impact its application for real-time applications. To improve the matching efficiency, we proposed a new parallel sclera vein recognition method using a two-stage parallel approach [...]

Automatic user state recognition for hand gesture based low-cost television control system

 ABSTRACT                                  An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal computer (PC), is designed to be flexible and to meet a wide range of end-user needs. Embedded systems [...]
