What is OFDM modulation technique?

Orthogonal Frequency Division Multiplexing (OFDM) is another widely used modulation method used to achieve high data rates and spectral efficiency. It is known as a multicarrier modulation method as many carriers are used instead of just one.

What is OFDM and how it works?

Orthogonal frequency-division multiplexing is a method of data transmission where a single information stream is split among several closely spaced narrowband subchannel frequencies instead of a single Wideband channel frequency.

Is OFDM modulation or multiplexing?

Orthogonal Frequency Division Multiplexing (OFDM) is a digital multi-carrier modulation scheme that extends the concept of single subcarrier modulation by using multiple subcarriers within the same single channel.

Why OFDM is used in 5G?

It offers a minimum complexity and achieves good bandwidth efficiency. The low complexity of OFDM is a consequence of the fact that each OFDM symbol is synthesized as a summation of a number of pure tones that are modulated by a set of quadrature amplitude modulated (QAM) data symbols.
