"Mobile terminal for a wireless communication system, wireless and.The process to share a frequency reference signal in a wireless mobile terminal between a wireless transceiver and a receiver for global positioning system (GPS), a mobile terminal without fIo for a wireless communication system comprises a wireless transceiver, a global positioning system receiver (GPS).In the wireless transceiver and the GPS receiver share a reference signal of frequ00b3u00eancia.The reference signal of frequ00b3u00eancia can be multiplied by an integer multiple to create a first local oscillator to a signal conversion to an intermediate frequ00b3u00eancia processingThe signal of the GPS signal.In addition, the reference signal of frequ00b3u00eancia can also be divided into a lower frequ00b3u00eancia to create a second local oscillator to a coversu00e3o a second frequ00b3u00eancia intermediate.The reference signal of frequ00b3u00eancia can also be divided to create a frequ00b3u00eancia necessary for other signal processing,As a sign of sampling analog to digital converter in the GPS receiver.The reference signal of frequ00b3u00eancia can be taken from different places within the system for the synthesis of frequ00b3u00eancia of wireless transceiver.For example, in one implementation, the reference signal of frequ00b3u00eancia is a sign of reference oscillator.In another implementation, the reference signal of frequ00b3u00eancia is a sign of radiofrequ00b3u00eancia,And in another implementation, the reference signal of frequ00b3u00eancia is a control signal of radiofrequ00b3u00eancia.Frequ00b3u00eancia error can be removed from the reference signal of frequ00d9u00eancia locking to a carrier of the base station.
