发明名称 Apparatus and method for improving GPS receive sensitivity in mobile terminal
摘要 Provided is a Global Positioning System (GPS) receive sensitivity-improving apparatus and method in a Code Division Multiple Access (CDMA) mobile terminal, which improves a GPS receive sensitivity by preventing a reference frequency variation caused by a thermal transient in the CDMA mobile terminal. The mobile terminal includes a transmitter equipped with CDMA/PCS (Personal Communication System) Power Amplifying Modules (PAMs) and a receiver equipped with a CDMA/PCS reception module and a GPS reception module. The CDMA/PCS PAMs remain turned on irrespective of the mobile terminal's operation modes. The CDMA/PCS reception module is turned on in a CDMA/PCS mode, and the GPS reception module is turned on in a GPS mode. The GPS receive sensitivity-improving apparatus and method prevents a GPS receive sensitivity from being affected by a module arrangement on the PCB of the mobile terminal, thereby making it possible to manufacture smaller, lighter and more compact mobile terminals.
