Introduction of CDMA TECHNOLOGY


ABSTRACT

Code-Division Multiple Access, a digital cellular technology that
uses spread-spectrum techniques. Unlike competing systems, such
as GSM, that use TDMA, CDMA does not assign a specific frequency
to each user. Instead, every channel uses the full available spectrum.
Individual conversations are encoded with a pseudo-random digital
sequence.
As the term implies, CDMA is a form of multiplexing which allows
numerous signals to occupy a single transmission chann ....etc

CDMA technology


INTRODUCTION :-

Code division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA employs spread-spectrum technology and a special coding scheme (where each transmitter is assigned a code) to allow multiple users to be multiplexed over the same physical channel. By contrast, time division multiple access (TDMA) divides access by time, while frequency-division multiple access (FDMA) divid ....etc

CDMA Technology

Abstract :

CDMA was developed by QUALCOMM Incorporated, a company in San Diego, California. QUALCOMM engineers decided to do something different and applied spread spectrum techniques to a multiple access system, which ultimately became CDMA.
In spread spectrum, instead of giving each person a channel, or each group of 3 or 8 people a time slot, CDMA puts everyone in the same channel at the same time.
At first thought, it would seem to be an impossible task to make work, but it does work. The reason it works is expla ....etc
