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.
