ABSTRACT

Network operators, service providers and customers are players who have different interests and raise different requirements on the functionality of future mobile communication networks. However, some new capabilities, such as mobility, security, ubiquity and quality are spelled out by all, which means that there exist some fundamental mechanisms which are in fact needed in every network. This paper concentrates on critical elements of the network infrastructure which need to be deployed in 4G networks before services can be offered ....etc

ABSTRACT
The aim of this paper is to describe the implementation of a lowpower,low-cost 16-bit RISC microcontroller that will act as thecore of a stand-alone security system. The controller is designedto provide moderate-high security at very low cost and to be ableto operate independent of a database. It is designed using 1.5-mSCMOS process from MOSIS and operates at a frequency of 12.5MHz.

CHAPTER 1.
INTRODUCTION
¢ This section provides a brief introduction to needs of implementing IP based 4G network.
Virtually all papers with the title ˜Beyond 3G Mobile Networks™ consider IP as the final means of integrating access networks from any technology”wireless or fixed” and the, equally IP-based, core network. This migration from traditional circuit-switched networks toward a packet based IP network infrastructure adds considerably to the pressure to provide commercialized services in this network. Although ....etc

Abstract-


Comparator-controlled power switch has been widely used to improve power efficiencies of discontinuous-conductionmode (DCM) buck regulators. Some major design challenges are capabilities of the comparator to operate at low voltage and dissipat ....etc

LOW-POWER LOW -AREA MULTIPLIER BASED ON SHIFT AND ADD ARCHITECHTURE
Multipliers
Multipliers are among the fundamental components of many digital systems
The largest contribution to the total power consumption in the multiplier is due to the generation of partial product
Among all the multipliers shift and add multipliers are the most commonly used ,due to its simplicity & relatively small area requirement
Mul ....etc
