This article describes a DDR SDRAM (Double Data Rate Synchronously
Dynamic RAM) controller. The commands of the FPGA-based DDR
SDRAM controller is described in detail. The Verilog HDL is used to implement the R/W operation of the DDR SDRAM. This controler isused to control a 400MHz single channel high-speed, high-precision and large-capacity data acquisition board.

Introduction
The speed and precision of data acquisition system must be sufficiently high to meet the requirements of advanced communication technology development. h ....etc

Radio frequency Identification Based public Transport Management
Radio frequency identification
 Radio frequency identification (RFID) is a generic term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object or person wirelessly, using radio waves.
 It's grouped under the broad category of automatic identification technologies.
The control station con ....etc

Mobile wireless communication services have penetrated into many people s daily works and lives. The contents of communication have also shifted from voice-dominating applications to multimedia services.




A common feature people traveling onboard high-speed public transport vehicles is that their journeys last for hours or even days. They would like to make use of these few hours to make telephone calls, read/send e-mails, browse a website or catch up on some work. There are also passengers who wish to have real on-demand entertainm ....etc

Intelligent public transport system for metro cities



EXISTING METHOD

Public transportation, mainly bus transport system has
been the most used means of transportation in India.

But it has been seen that commuters are most of the time
kept waiting in the bus stand for long time .

With millions of people using this public bus transport system,
would it not be nice and worthy to provide real time update of
bus location and approximate ....etc

high speed underwater acoustic modems is shown in this paper. high speed digital communication and broadband underwater acoustics technologies have been combined to achieve this . increased data rate and decreased power consumption is achieved by Broadband Spread Spectrum Technology. The underwater communication has to deal with noises such as offshore drilling noise, ambient noise, ship noise etc. no communication errors has been seen to appear with these noises.
Broadband Spread Spectrum Technology us implemented ....etc

High-Speed Circuit Board Signal Integrity



Characteristics and Construction of
Printed Wiring Boards

Introduction

This is a book about high-speed signaling on printed wiring boards (PWBs). The
physical construction of PWBs determines the conductor’s resistance (discussed in
Chapter 2), its self capacitance (covered in Chapter 3) and inductance (Chapter 4),
and the coupling to neighboring conductors (Chapters 5 and 9). At the high frequencies
of interest in this book, these electrical primi ....etc
