Abstract
A multicarrier receiver which receives a cyclically extended multicarrier symbol which is in a serial format is provided. The multicarrier receiver includes a serial to parallel converter, a window which decreases spectral side lobes of the multicarrier symbol and outputs a windowed multicarrier symbol, a difference term generating unit which generates difference terms from the multicarrier symbol in parallel format, a first Fourier transformer which fast Fourier transforms a single carrier of the windowed multicarrier symbol for all carriers of the windowed multicarrier symbol and outputs a first Fourier transformed carrier, a second Fourier transformer which fast Fourier transforms difference terms, and a per-carrier frequency domain equalizer which equalizes all frequencies by deriving necessary fast Fourier transforms utilizing linear combinations of the first fast Fourier transformed carrier, one or more non-windowed fast Fourier transformed carriers from the second Fourier transformer and the difference terms.
