Abstract:
1. A mobile communication device with positioning capability, comprising: a global navigation satellite system (GNSS) receiver; a communication circuit, for generating a control signal; an oscillator, shared between the communication circuit and the GNSS receiver, controlled by the control signal of the communication circuit to provide a clock signal having a frequency value corresponding to the control signal to the GNSS receiver and the communication circuit; and a decision unit, coupled to the communication circuit and the GNSS receiver, having at least a storage unit configured for recording digital information represented by the control signal, wherein the digital information is a control voltage of the oscillator, and the decision unit detects and records a voltage value of the control voltage; wherein the GNSS receiver obtains the frequency value of the clock signal according to the voltage value recorded in the decision unit.
