Abstract

An equalizing device with notch compensation for a direct conversion receiver is disclosed. The baseband signal of a direct conversion receiver comprises a notch in the frequency response after the required DC compensation is performed. A bandpass generates a notch compensation signal on from a decision signal and a interference compensation signal of a decision feedback loop. Therefore, the reliability of the decision signal is enhanced and allows an improved data rate in WLAN applications.
