WIRELESS COMMUNICATION DEVICE AND ASSOCIATED METHOD INCLUDING CONTROL OF POSITIONING-SYSTEM RECEIVER AND SHARED OSCILLATOR |
摘要 |
<p>The wireless communication device includes a wireless communication transceiver to generate an oscillator control signal and an activation signal, a positioning-system receiver (e.g. a GPS receiver) to process received positioning signals, and a shared oscillator (e.g. a temperature compensated and voltage controlled crystal oscillator TCVCXO) responsive to the oscillator control signal and to generate a reference frequency signal for the wireless communication transceiver and the positioning-system receiver. The positioning-system receiver may control processing of the received positioning signals based upon the activation signal to reduce a noise contribution (e.g. phase noise) due to frequency control of the shared oscillator based upon the oscillator control signal. The activation signal may indicate that the oscillator control signal is being varied to provide frequency control or adjustment of the shared oscillator.</p> |
