Abstract
The cell phone market has grown dramatically over the past 5
years and has become one of the highest volume consumer products in the
world. Competition in this market has driven costs down and phone features
higher, making the design of cell phones more and more challenging. GSM
phones account for approximately 80% of the entire cell phone market.
In this presentation we give a brief introduction to the GSM system and
discuss some of the trends in the cell phone industry. Receiver, transmitter
and digital baseband architectures will be overviewed. The evolution of
these architectures over the past several generations of cell phones will be
discussed.
