Method embodiments are provided herein for dynamically calibrating and adjusting a direct conversion receiver system. One embodiment includes applying one or more gain control signals to one or more gain elements of a receiver system, where the applying one or more gain control signals results in a gain change to the receiver system; in response to the gain change, determining whether the receiver system exhibits a DC (direct conversion) offset; and in response to a determination that the receiver system exhibits the DC offset, applying one or more DC offset correction control signals to one or more gain elements of the receiver system, where the one or more DC offset correction signals are configured to correct the DC offset.

Systems and methods to dynamically calibrate and adjust gains in a direct conversion receiver

A method of processing location information on a mobile device which includes a primary receiver for receiving a primary signal; a diversity receiver for receiving a diversity signal or location information; a diversity combiner which can combine primary and diversity signals to form a combined signal; and a first processing unit for processing the combined signal; the method comprising the steps of: identifying whether the device is in a location mode or a diversity mode; if the device is in location mode, disabling the diversity combiner; passing the output from the primary receiver directly to the first processing unit; and passing location information from the diversity receiver to a location processing unit.
