OFDM definition

Before we learn about OFDM, first let we check it out what is full form of OFDM. OFDM is a modulation format used for the latest wireless communications technology. 

OFDM is a multi-carrier transmission technology. OFDM is used to obtain a higher data rate in the multipath fading environment of mobile communication.

In mobile communication, the selection of digital modulation is dependent on three parameters. They are listed below :
  • Narrower bandwidth 
  • Efficient power utilization
  • Elimination of intermodulation products
