Applications of CDM
- CDM is widely used in second generation (2G) and third generation 3G wireless communication. These systems are used in Ultra High Frequency (UHF) mobile phones in the 800 MHz and 1.9 GHz bands. It is a combination of analog-to-digital conversion and spread spectrum techniques.
- CDM network technology is used to combine multiple data signals for simultaneous transmission on multiple frequency lines.
- This type of multiplexing is commonly used in 2G & 3G wireless communications.
- It is used in UHF (Ultra High Frequency) mobile phones in the 800 MHz and 1.9 GHz bands. So it’s a combination of analog-to-digital conversion and spread spectrum technology.
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.
