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.

Method and apparatus to receive location information in a diversity enabled receiver

According to an exemplary embodiment, a circuit includes a power amplifier configured to generate an RF output signal. The circuit further includes a pulse shaping circuit coupled to the power amplifier, where the pulse shaping circuit is configured to receive a digital input signal and generate an analog output signal at a first node, and where the analog output signal controls the RF output signal. The analog output signal has a ramp-up portion having a first shape, where the first shape corresponds to a piece-wise-linear approximation of a sinusoid. The analog output signal also has a ramp-down portion having a second shape, where the second shape corresponds to the piece-wise-linear approximation of a sinusoid. The pulse shaping circuit does not require a clock reference to generate the analog output signal.
