Code Division Multiplexing
Code division multiplexing is a multiplexing process in which various information can be combined for instantaneous transmission of a frequency band. This multiplexing technique is used to allow multiple users to send a single communication, it is called CDMA or Code Division Multiple Access. It does not affect the bandwidth of the digital signal or frequency. It has less interference, thus providing a better and safer method of communication. The number division multiplexing scheme is shown below. The chart below shows how each transmission method works simultaneously. CDM uses spread spectrum technology in wireless communication because each channel is encoded to broadcast over a wider range than the original signal used.
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.
