PRESENTED BY: S ADITYA THIMMA REDDY PUSHPAVALLI R P VENKATA KRISHNA TEJA S PENNA OBULAMMA Abstract Spread-spectrum telecommunications is a signal structuring technique that employs direct sequence, frequency hopping, or a hybrid of these, which can be used for multiple access and/or multiple functions. This technique decreases the potential interference to other receivers while achieving privacy. Frequency-hopping spread spectrum (FHSS), direct-sequence spread spectrum (DSSS ....etc [:=Read Full Message Here=:]

Abstract: Spread spectrum is a form of wireless communications in which the frequency of the transmitted signal is deliberately varied. This result in a much greater bandwidth than the signal would have if its frequency were not varied.A conventional wireless signal has a frequency, and are methods by which electromagnetic energy generated in a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth usually specified in megahertz (MHz) or gigahertz gigahertz), that doe ....etc [:=Read Full Message Here=:]

Title: Image Watermarking Using Spread Spectrum Technique in Log-2-Spatio Domain Page Link: Image Watermarking Using Spread Spectrum Technique in Log-2-Spatio Domain - Posted By: seminar class Created at: Thursday 05th of May 2011 02:25:33 PM	advantage of log periodic antenna ppt, spread spectrum and multiple access technique, what is the aim of spread spectrum image watermarking with digital design, advantages log periodic antenna, spread spectrum cpu, spatio temporal network, hdfccredit card log,
Abstract In this paper, we propose to embed the watermark information in the log-2-spatio domain by means of spread spectrum technique. In log-2-spatio domain, the variance of the information is reduced significantly. This improves the efficiency and robustness of spread spectrum technique. Low intensity and mid-band regions are selected to embed the information in order to guarantee an invisible watermark as well as the robustness to JPEG compression. Simulation results show that the embedded information still survive up to ....etc [:=Read Full Message Here=:]

Much of the signal processing performed in modern wireless communications systems—such as digital modulator/demodulator applications—takes place in the digital domain and requires high throughput. Dedicated hardware can provide the processing capability to meet this requirement. The parallel processing capability of Altera® programmable logic devices (PLDs) makes them ideal for baseband/intermediate frequency (IF) digital signal processing applications. The direct sequence spread spectrum (DSSS) digital modem reference design is ....etc [:=Read Full Message Here=:]

1.1WHAT IS SPREAD SPECTRUM? Spread-spectrum techniques are methods by which a signal (e.g. an electrical,electromagnetic, or acoustic signal) generated in a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth. These techniques are used for a variety of reasons, including the establishment of securecommunications, increasing resistance to natural interference and jamming, topreventdetection, and to limit power flux density (e.g. in satellite downlinks).

1. Abstract In recent time watermarking technique becomes a potential solution for copyright protection, authentication and integrity verification of digital media. Among the widely used watermarking techniques, spread spectrum modulation based method becomes appealing due to its inherent advantage of greater robustness and is used widely for various applications. Some watermarking applications, for example, digital television broadcasting, internet protocol television (IP-TV), etc. essentially demand development of ....etc [:=Read Full Message Here=:]

1. INTRODUCTION Code Division Spread Spectrum is one form of CDMA communication technique optimized for the cost conscious, high volume and short cycle consumer electronics market. Its primary application is in digital cordless telephony today. Meanwhile, it is being applied to wireless devices for the last 100-meter connection to the Internet, and in the wireless local loop to provide sub-$20 handset cost, tariff free mobile voice services in some third world countries. Why is CD/SS technology suitable for consumer e ....etc [:=Read Full Message Here=:]

ABSTRACT A novel data-hiding methodology, denoted as digital invisible ink (DII), is proposed to implement secure steganography systems. Like the real-world invisible ink, secret messages will be correctly revealed only after the marked works undergo certain prenegotiated manipulations, such as lossy compression and processing. Different from conventional data-hiding schemes where content processing or compression operations are undesirable, distortions caused by prenegotiated manipulations in DII-based schemes are indispensable steps for ....etc [:=Read Full Message Here=:]
