Digital detection of blockers for wireless receiver

Abstract

A receiveris provided. The receivercomprises an in-phase analog-to-digital converteroperable to detect a saturation condition of the in-phase analog-to-digital converterand to adjust the amplitude of a in-phase signal processed by the in-phase analog-to-digital converterto remove the in-phase analog-to-digital converterfrom the saturation condition and a in-phase digital filteroperable to adjust a gain applied to a digital input to the in-phase digital filterfrom the in-phase analog-to-digital converter, 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. In an embodiment, the receiveralso 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 converterand the in-phase digital filtercomprise an intermediate frequency receiver.
