What is OFDM (Orthogonal Frequency Division Multiplexing)?
Orthogonal FDM is simply a type of digital communication technique that is developed for using in cable system mostly. In the case of wireless communication, OFDM is like as single carrier modulation as frequency division multiple access (FDMA), time-division multiple access (TDMA), and code-division multiple access (CDMA).
Difference between TDM and FDM
TDM (Time Division Multiplexing) and FDM (Frequency Division Multiplexing) both are multiplexing techniques where TDM is used in both analogue and digital signals. In contrast, FDM is only used in analogue signals. Here we will discuss both TDM and FDM in detail and we will also see the differences between these two.
