摘要:
A receiver 100 is provided. The receiver 100 comprises an in-phase analog-to-digital converter 112 operable to detect a saturation condition of the in-phase analog-to-digital converter 112 and to adjust the amplitude of a in-phase signal processed by the in-phase analog-to-digital converter 112 to remove the in-phase analog-to-digital converter 112 from the saturation condition and a in-phase digital filter 114 operable to adjust a gain applied to a digital input to the in-phase digital filter 114 from the in-phase analog-to-digital converter 112, the adjustment of the gain substantially inversely proportional to the adjustment of the amplitude of the in-phase signal processed by the in-phase analog-to-digital converter 112. In an embodiment, the receiver 100 also comprises a quadrature path that is substantially similar to the in-phase path, and the in-phase path and the quadrature path comprise a direct conversion receiver. In an embodiment, the in-phase analog-to-digital converter 112 and the in-phase digital filter 114 comprise an intermediate frequency receiver.
