THE ROLE OF VLSI AND SDR TO MAKE MOBILE AFFORDABLE AND FLEXIBLE
[attachment=50650]
INTRODUCTION
SDR Plays a prominent role in the mobile communication
Tele communication industry is one of the highly developed segment which is dependent on VLSI technology
VLSI helps in reducing the size and price of the mobile
Networks in Telecommunication
GSM (Global System for Mobile communication)
CDMA (Code Division Multiple Access)
VLSI TECHNOLOGY
Digital VLSI circuits are predominantly CMOS based
VLSI is the next stage of SSI and MSI.
Packing more and more logic devices into smaller and smaller areas particularly in this era of Nano technology simplicity plays a very prominent role for any device is possible by using VLSI design
RF TECHNOLGY
When an RF current is supplied to an antenna, it gives rise to an electromagnetic field that propagates through space
RF Transmitter,RF Receiver,Encoder and Decoder
Main requirements for the Communication using RF
INVOLVES IN TWO CONCEPTS
Ideal concept
A digital signal processor would read the converter and its soft ware would transform the stream of data form the converter to any other form it requires
FINAL WORD
In countries like India, price place an important role in determining the demand for a particular product, and also interest towards compact and simple devices is increasing day by day
With the advent of SDR one needs just one set to access different networks, thereby, providing flexibility
