Abstract
A receiver circuit includes a conversion circuit configured to down-convert a received radio-frequency signal to a baseband signal, an analog-to-digital converter configured to sample the baseband signal into a sampled signal, a Fast Fourier transform (FFT) circuit configured to perform an FFT on the sampled signal, and a digital compensation circuit configured to compensate for IQ distortion in a frequency domain.
