Multicarrier modulation helps to reduce the detrimental effects of multipath fading. Because of its
robustness to multipath, and the ease of implementating it in transmitters and receivers using the
fast Fourier transform (FFT), the MCM concept is growing rapidly in practical importance. It can
be found today in IEEE standards 802.11a, 802.15.3 and 802.16a, as well as standards for digital
broadcasting of television and radio. This document serves to derive the multicarrier modulation
method from first principles.
