ABSTRACT:
A communication system may include an equalizing device for DC-offset mitigation. The system includes: an input analog-to-digital converter configured to receive an input signal and produce a digital signal from the input signal; and a DC-offset estimation device coupled with the input analog-to-digital converter. The DC-offset estimation device is configured to produce a quantized DC-offset estimate from the digital signal. And the input analog-to-digital converter is configured to receive the quantized DC-offset estimate and to adjust a DC offset of the digital signal.
