Abstract
A multicarrier receiver (RX′) comprises the cascade connection of a sliding Fourier transformer (SLIDING FFT) which subsequently Fourier transforms parts of an incoming cyclically extended multicarrier symbol (MS), and a per-carrier frequency domain equaliser (PC-FEQ) including for each carrier a tapped delay line (TD TD , . . . , TDN/ ) for equalising the Fourier transformed parts of the incoming multicarrier symbol (MS). The per-carrier frequency domain equaliser (PC-FEQ) allows to optimise the system capacity individually per carrier, and in a preferred embodiment of the invention includes tapped delay lines (TD TD , . . . , TDN/ ) with adaptive complex taps, with an adaptive length and with an individual delay that may differ for different carriers.
