Advantages of CDM
- It has better signal quality.
- Since the sender and receiver only know the spreading code, it prevents eavesdropping and disturbance.
- Protected from hackers.
- Adding users is easy and there is no limit to the number of users.
- Large signal bandwidth reduce multipath fading.
- Effective use of private spectrum.
- Resource allocation is flexible.
- It is very efficient process.
- No synchronization required.
- In this multiplexing, many users can share the same bandwidth.
- CDM is scalable.
- Compatible with other types of cellular technology.
- Uses a fixed frequency spectrum.
- The interference was reduced due to different code words assigned to each user.
- Enhance security, avoid crashes and collisions, and use bandwidth effectively. CDMA’s spread spectrum technology makes it difficult for eavesdroppers to catch signals, and the special spread spectrum code makes it possible to avoid interference and block transmission.
Code Division Multiplexing
Multiplexing is a method that can be used to send multiple analog or digital signals over communication channels such as radio waves or fiber optic cables and convert them into a single signal. When the destination is reached, the signal is demultiplexed. The main purpose of using this method is to share limited resources. A real-world example of multiplexing is in the telecommunications industry, where multiple calls can be made using a single connection.
