Multicarrier receiver

Abstract

A Multicarrier receiver suitable to receive a sequence of cyclically extended multicarrier symbols comprises the coupling of a window, adapted to window said multicarrier symbols, a Fourier transformer, coupled to said window, and adapted to perform one windowed Fourier transform for all carriers in said windowed multicarrier symbol, a per-carrier frequency domain equalizer, coupled to said windowed Fourier transformer and comprising a tapped delay line per carrier in said multicarrier symbol, and means for performing the equivalent to a sliding windowed Fourier transform, including a sliding Fourier transform. Thus windowing and equalization in the frequency domain can be combined without unduly increasing computational complexity.
