What is OFDM spectrum?

What is orthogonal frequency-division multiplexing (OFDM)? 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 spread spectrum?

OFDM can also be used as a spread spectrum modulation (OFDM-SS) [3, 4, 5] wherein spectral spreading is accomplished by putting the same data on all the carriers, producing a spreading factor equal to the number of carriers.

What is the basic fundamental principle of OFDM system?

The OFDM concept is based on spreading the high speed data to be transmitted over a large number of low rate carriers. The carriers are orthogonal to each other and frequency spacing between them are created by using the fast Fourier transform (FFT).
