4G Wireless Systems

Abstract :

The ever-increasing growth of user demand, the limitations of the third generation of wireless mobile communication systems and the emergence of new mobile broadband technologies on the market have brought researchers and industries to a thorough reflection on the fourth generation. Many prophetic visions have appeared in the literature presenting 4G as the ultimate boundary of wireless mobile communication without any limit to its potential, but in practical terms not giving any design rules and thus any ....etc

Abstract:

This paper gives a brief idea of how the mobile communication has evolved,its generations. Different generations have been developing since then each generation coming out overcoming previous generation drawbacks.One such technology in fourth generation is OFDM. OFDM based technique looks more promising as a 4G standard surpassing the 3G standards .So,a complet ....etc

ABSTRACT

Traditionally, input shaping has been used outside the feedback control loop. Utilizing input shaping in this way prevents it from directly addressing some important vibration control issues such as disturbances, nonzero initial conditions, actuator saturation, etc., These potential applications, however, will never be fully exploited unless a good understanding exists of how to create stable CLSS controllers.

Study of closed-loop stability of feedback loops containing input shapers by ana ....etc

Introduction

Pick up any newspaper today and it is a safe bet that you will find an article somewhere relating to mobile communications. If it is not in the technology section it will almost certainly be in the business section and relate to the increasing share prices of operators or equipment manufacturers, or acquisitions and take-overs thereof. Such is the pervasiveness of mobile communications that it is affecting virtually everyoneâ„¢s life and has become a major political topic and a significant contributor t ....etc

THREE PHASE DUAL CONVERTER
Introduction
Thyristor based three-phase controlled rectifiers are widely used in the industry for controlling dc motor drives. Controlled rectifiers offering power conversion from ac to dc are reliable and have higher lifetime compared to other converters. DC motors have higher torque than ac motors and hence are suitable for variable speed and speed reversing applications requiring high torques. Although the operation of controlled rectifiers is simple, the realization of the converter control circuit is complex ....etc

Fourth Generation (4G) wireless communications



1. What is fourth generation (4G) mobile?


At present the download speed for mobile internet connections in Japan are between 9.6 kbit/s for 2G cellular, up to 128 kbit/s for PHS, typically 200 kbit/s (nominally 384 kbps) for DoCoMo and Vodafone 3G cellular, and 2.4 Mbps for KDDI/AU CDMA2000-1x-WIN service. However, in actual use the data rates are usually slower, especially in crowded areas, or when the n ....etc

Introduction of Fourth-Generation Cellular Communication System



Third Generation Cellular Communication(3G) 

3G networks provide the ability to transfer voice data and non-voice data (music downloads, emails and instant messaging) over the same network simultaneously.
3G networks deliver broadband capacity and support greater numbers of voice and data customers at lower incremental costs than 2G.

Fourth Generation Cellular Communication (4G)

4G is not one defined technology or standard ....etc

ECE Fourth Year Design Project Database
Secure Authenticated Transceiver 2006.002
Secure delivery of digital content requires end-to-end security in which encryption and decryption occur at the point of analog data I/O. We present a novel communications protocol and a prototype device, the Secure Authenticated Transceiver (SAT), to satisfy this need. The prototype is implemented on an embedded processor on a development board. The envisioned system, in which SATs can open secure, authenticated sessions with one another or with a ....etc

ABSTRACT

A laser-based contact less displacement measurement system is used for data acquisition to analyze the mechanical vibrations exhibited by vibrating structures and machines. The analysis of these vibrations requires a number of signal processing operations which include the determination of the system conditions through a classification of various observed vibration signatures and the detection of changes in the vibration signature in order to identify possible trends. This information is a ....etc
