Abstract: A frequency domain chip-level equalizer is disclosed. The equalizer includes an estimation module configured to generate a frequency domain estimate of an auto-correlation function of a received signal; and an equalization module configured to apply frequency domain equalization to the received signal using the frequency domain estimate of the auto-correlation function to generate frequency domain equalized samples of the received signal. The equalizer further includes an Inverse Fast Fourier Transform (IFFT) module configured to generate time domain equalized samples of the received signal from the frequency domain equalized samples.
