What are the basic features of OFDM?

In OFDM, several bits can be sent in parallel, or at the same time, in separate substream channels. This enables each substream's data rate to be lower than would be required by a single stream of similar bandwidth. This makes the system less susceptible to interference and enables more efficient data bandwidth.

What are the limitations of OFDM?

The main drawbacks of OFDM are its high peak to average power ratio and its sensitivity to phase noise and frequency offset.

In which applications we can use OFDM?

Orthogonal frequency division multiplexing (OFDM) is a modulation technique that is used in several applications ranging from cellular systems (3GLTE, WiMAX), wireless local area networks (LANs), digital audio radio, underwater communications, and even optical light modulation.
