Radio and Soft Ware
ABSTRACT: This is the world of VLSI . Presently all most all the people are using technology in various forms like mobiles, i-pods, i-phones etc., Every one enjoys technology but only a few know about VLSI design in world design and its working. Coming to VLSI it is the process of creating integrated circuits by combing 1000`s of transistor based circuits in to a single chip. It began 1970`s when complex semi conductors and communication technologies were being developed, But now it has become key to many sophisticated electronic devices. As the subject is a big ocean we laid our emphasis on VLSI chip coupled with SDR technology used in mobiles. VLSI technology makes the mobile affordable and SDR technology make its flexible. Coming to the role of soft ware define radio abbreviated as SDR, it helps one to access different net works like CDMA, GSM, WILL etc. Basically SDR is radio communication system which can potentially tune to any frequency band and received any modulation across a large frequency spectrum by means of little hard ware as possible and process it signals through soft ware.

This paper introduces the basic design of SDR, use of VLSI chips in mobiles and their working principles.
KEYWORDS:-
1. VLSI - Very large scale integration 2. SDR - Soft ware defined Radio 3. R.F - Radio Frequency 4. I.F -intermediate frequency
INTRODUCTION
Tele communication industry is one of the highly developed segment which is dependent on VLSI technology. SDR also plays a prominent role in the mobile communication VLSI helps in reducing the size and price of the mobile where as SDR increases the flexibility of the mobile.
Existing networks in telecommunication can be classified into two major types -
a) GSM (Global System for Mobile communication)
b) CDMA (Code Division Multiple Access)
These networks differ in their accessing frequencies. The problem
