Frequency adjustment in combined mobile communication-positioning device

摘要

Systems and techniques are disclosed relating to wireless communications. These systems and techniques involve wireless communications wherein a device may be configured to recover an information signal from a carrier using a reference signal, detect a frequency error in the information signal; and periodically tune the reference signal to reduce the frequency error. To prevent GPS performance degradation during LO tuning, a tuning indicator signal may be generated and provided to the GPS receiver to disable GPS operation.
