INTRODUCTION
WCDMA stands for Wide Band Code Division Multiple Access.
W-CDMA is a Third-Generation(3G) mobile wireless technology that promises much higher data speeds to mobile and portable wireless devices than commonly offered in today's market.
It is specified by 3rd Generation Partnership Project (3GPP).
It is the key technology for UMTS.
HISTORY
QUALCOMM , the first company to succeed in developing a practical and cost effective CDMA implementation for co ....etc

Security for the Third Generation (3G) Mobile System


1 Introduction
When considering security in mobile systems, in common with most other systems, our main
objectives are in preventing:
Access and use of service to avoid or reduce a legitimate charge.
Loss of confidentiality or integrity of a user s or operator s data
Denial of a specific user s access to their service or denial of access by all users to a service
However, user expectations for instant communication ....etc

ABSTRACT

So far transmission errors have been described as evil entity in communication literature. Introducing error intentionally can save power and reduce interference. This has been proved by scientists Jik Dong Kim (South Korea), Sang Wu Kim (USA) and Young Gil Kim (South Korea). It is about combined power and error control in multicarrier DS-CDMA systems ....etc

Abstract:

This paper presents the design, implementation and test results of a complete wideband CDMA modem with a modulator and a demodulator for use in next-generation mobile stations. The modem is based on NTT DoCoMo's proposal for the next generation W-CDMA air interface. The modulator supports multicode transmission capability, which enables three dedicated physical channels to be t ....etc

Topic: fuzzy based call admission control in wideband cdma cellular networks

ABSTRACT
In this paper, a novel call admission control (CAC) scheme using fuzzy logic is proposed for the reverse page link transmission in wideband code division multiple access (CDMA) cellular communications. The fuzzy CAC scheme first estimates the effective bandwidths of the call request from a mobile station (MS) and its mobility information, and then makes a decision to accept or reject the connection request based on ....etc

PERFORMANCE ANALYSIS OF WIDEBAND CDMA SYSTEMS IN A LOGNORMAL FADING CHANNEL

ABSTRACT

In this letter, the performance of a wideband CDMA system in the presence of Lognormal fading is studied. The wideband CDMA system, modeled using Gaussian Approximation is analyzed on a slow fading Lognormal channel which fades the amplitude of the transmitted signal according to the Lognormal Distr ....etc
