Abstract:
1. A wireless mobile station, comprising: a baseband subsystem including a controller and a signal processing unit operatively connected to the controller, the baseband subsystem being operable to generate one or more synthesizer control signals; and a radio frequency subsystem operatively connected to the baseband subsystem, the radio frequency subsystem including: a transmitter operable to obtain transmit signals from the baseband subsystem, process the transmit signals and to send out the processed transmit signals from the wireless mobile station; a plurality of synthesizers, a first one of the plurality of synthesizers being operable to generate a first local oscillating signal and a second one of the plurality of synthesizers being operable to generate a second local oscillating signal; and a plurality of radio frequency receive chains operable to receive signals from at least one base station, to process the received signals and to send the processed received signals to the baseband subsystem, a first one of the plurality of radio frequency receive chains receiving the first local oscillating signal from the first synthesizer in a first mode of operation according to the one or more synthesizer control signals, the first radio frequency receive chain receiving the second local oscillating signal from the second synthesizer in a second mode of operation according to the one or more synthesizer control signals, and a second one of the plurality of radio frequency receive chains receiving the first local oscillating signal from the first synthesizer in both the first and second modes of operation.
