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

Introduction to cdma2000 Standards for Spread
Spectrum Systems


OVERVIEW

The cdma2000 Family of Standards
The cdma2000 family of standards includes core air interface, minimum performance, and
service standards (see 1.3). The cdma2000 air interface standards specify a spread
spectrum radio interface that uses Code Division Multiple Access (CDMA) technology to
meet the requirements for Third Generation (3G) wireless communication systems. The
core air interface standards in the family are [ ....etc

Abstract

We present a new method of digital steganography, entitled spread spectrum image steganography (SSIS). Steganography, which means covered writing in Greek, is the science of communicating in a hidden manner. Following a discussion of steganographic communication theory and review of existing techniques, the new method, SSIS, is introduced. This system hides and recovers a message of substantial length within digital imagery while maintaining the original image size and dynamic range. The hidden message can be recovered using appropr ....etc

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
