Multiplexing is the process of combining multiple signals into one, in such a manner that each individual signal can be retrieved at the destination. frequency division multiplexing (OFDM) scheme because of various advantages. Like all multi-carrier systems, OFDM benefits from dividing a high data rate stream into several parallel, low data rate streams that are transmitted on different subcarriers, which allows to exploit frequency diversity.

Frequency Division Multiplexing (FDM) is a networking technique in which multiple data signals are combined for simultaneous transmission via a shared communication medium. FDM uses a carrier signal at a discrete frequency for each data stream and then combines many modulated signals. When FDM is used to allow multiple users to share a single physical communications medium (i.e. not broadcast through the air), the technology is called frequency-division multiple access (FDMA).

Frequency-division multiplexing (FDM) can be used in both wired and wireless networking for transmitting large amounts of data at high speeds. Frequency-division multiplexing (FDM) is an analog technique that can be applied when the bandwidth of a link is greater than the combined bandwidths of the signals to be transmitted. In FDM, signals generated by each sending device modulate different carrier frequencies.

Frequency-Division Multiplexing (FDM) is a scheme in which numerous signals are combined for transmission on a single communications line or channel. It is analog multiplexing technique. Each signal is assigned a different frequency (sub channel) within the main channel. its requires channel synchronization.

In the above diagram, a single transmission medium is subdivided into several frequency channels, and each frequency channel is given to different devices. Frequency division multiplexing is a defined as a type of multiplexing where the bandwidth of a single physical medium is divided into a number of smaller, independent frequency channels.

In this work, we investigate the performance of multicarrier index keying (MCIK) orthogonal frequency division multiplexing (OFDM) proposing a hybrid low 

Voice / phone call data arrives at frequencies between 300 Hz and 4000 Hz. Computer data arrives at a much higher frequency. Line splitters (filters) are used to separate these two signals.

Let us understand with the help of an example.

Frequency overlap is a serious issue when it comes to frequency division multiplexing and it must be completely avoided. Two frequency ranges can be separated by using some narrow frequency ranges called guard bands. The guard bands avoid signal interference and enhance the quality of communication.
