Patent ID: 7738572

Claim:
A receiver comprising: a demodulator for demodulating both an in-phase (I) component and a quadrature-phase (Q) component of a received signal to thereby generate I and Q time-domain serial data; a serial to parallel unit for converting the time-domain serial data to a plurality of parallel paths; a Fourier transform circuit for generating frequency domain samples from the time-domain samples; and an equalization and I-Q mismatch correction circuit being coupled to the Fourier transform circuit for performing both frequency domain equalization and I-Q mismatch correction on at least one frequency domain sample being output by the Fourier transform circuit; wherein the equalization and I-Q mismatch correction circuit is further for performing the I-Q mismatch correction on a per-tone basis; and wherein each particular tone has respective frequency domain equalization coefficients to correct the respective channel distortion and I-Q mismatch experienced by the particular tone.
