CDMA Full Form
What is the full form of CDMA?
The meaning of CDMA is code division multiple access. It is a method, or we can say it is a channel access method which is used by a lot of radio communication technologies.
It gives multiple access to the technologies. With the help of this method, a couple of transmitters can send information simultaneously on a single communication channel.
CDMA is extremely helpful in optimizing the use of available bandwidth. It transmits over the total frequency range and does not limit the user's frequency range.
This is a way of providing access to technology and also provides an air interface for wireless digital cellular form and other communication systems. The technique of CDMA was originally developed by Qualcomm. Qualcomm helps hold the patents for CDMA and is greatly beneficial.
CDMA provides access to wireless digital cellular. Therefore it has been used for a long time also due to the large path loss and Doppler shift caused by satellite motion. It is frequently used with Binary phase-shift keying (BPSK)and in its simplest form and can be easily combined with any modulation scheme like orthogonal frequency-division multiplexing (OFDM), which makes it efficient.
There are more other schemes that use subcarriers to enable a larger gap between the virtual center frequency and the subcarriers. CDMA uses technology with a special coding scheme.
Advantages of CDMA
- This is one of the advanced remote innovations which utilize spread-range strategies.
- CDMA reliably provides a better ability to voice and information correspondences comparatively to other business portable innovations.
It gives better multipath execution.
It has the most noteworthy range of effectiveness.
CDMA doesn’t require any synchronization.
Disadvantages of CDMA
In CDMA, time synchronization is needed.
It has a Self-sticking issue.
The CDMA system is more complicated.
With this technology, guard bands and guard time, both are required to be provided.
The overall quality of service gets decreased when the number of users increases.
