MCM (Multicarrier modulation)?

Multicarrier modulation (MCM) scheme is a procedure that changes the high-speed serial signals into various low-speed parallel signals. This extraordinary multicarrier modulation scheme was presented by Chang. It is also known as the orthogonal frequency division multiplexing (OFDM). An OFDM signal comprises a number of closely spaced modulated carriers. At the point when modulation of any form - voice, information, and so forth is applied to a carrier, then sidebands spread out one or the other side.
