Apparatus and method for substantially eliminating a near-channel interfering amplitude modulated signal |
摘要 |
An apparatus and method are provided that compensates for the problematic time-varying DC offset by effectively eliminating a near-channel amplited modulated interferer from a signal. The apparatus includes a first channel estimator for estimating a plurality of first channel filter taps H using a first signal model S<SUB>t</SUB>, and a second channel estimator for estimating a plurality of second channel filter taps H using a second signal model S<SUB>t</SUB>. The apparatus also includes a processor for selecting which of the first signal model S<SUB>t </SUB>and the second signal model S<SUB>t </SUB>is to be used or was used to substantially eliminate the near-channel amplitude modulated interferer from the received signal. The apparatus can be a mobile phone, base station, direct conversion receiver, or communications system (for example). |
