A Technical Seminar Report on VLSI GSM CDMA Technology.
[attachment=53056]
ABSTRACT:
Today the world is of VLSI and people are various forms of technology like mobiles, i-phones, i-pods, etc. VLSI is the method of creating integrated circuits into a single chip with the help of 1000 of transistor based on circuits. The emphasis is based on VLSI chip and SDR technology which are used in mobiles. VLSI technology makes the mobile affordable whereas SDR technology makes its flexible. SDR is radio communication process which tune to any frequency band over a large frequency spectrum.VLSI helps to decrease mobile size and price whereas SDR increases the mobile flexibility. This network telecommunication is classified into two major types. First one is GSM (Global System for Mobile communication) and second one is CDMA (Code Division Multiple Access). These two networks are different in accessing frequencies. The problem with these networks is that these two networks cannot be accessed from one mobile hand set. Today, dual SIM card mobile phones have been improving by using SDR.
Present VLSI designs are having three categories. They are Analog, Application Specific integrated circuits, and Systems on chip. Its advantages include Lower package count, low board space, fewer board level connections, higher performance, reliability and lower cost due to the lower chip count.
