Structural Mechanism and Applications of CDMA ppt | seminor topic free download

ABSTRACT

The world is demanding more from wireless communication
technologies than ever before. More people around the world are subscribing
to wireless services and consumers are using their phones more frequently.
Add in exciting Third-Generation (3G) wireless data services and
applications- such as wireless email, web digital picture taking/sending and
assisted GPS position location applications and wireless networks are asked
to do much more than just a few years ago. And these networks will be asked
to do more tomorrow.
This is where CDMA technology fits in. CDMA consistently provides
better capacity for voice and data communications than other commercial
mobile technologies, allowing more subscribers to connect at any given time.
CDMA is a “spread spectrum” technology, allowing many users to
occupy the same time and frequency allocations in a given band. As its name
implies, CDMA assigns unique codes to each communication to differentiate
it from others in the same spectrum. In a world of finite spectrum resources,
CDMA enables many more people to share the airwaves at the same time
than do alternative technologies.
In this project we have enlighten the basic functionality and the
drastic changes it brought in the modern communication era. Followed by the
capacious advantages it is having now a days.
