Abstract
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.
Claims36
A communications device, comprising:
- a tunable oscillator configured to produce a reference signal;
- a receiver configured to recover an information signal from a carrier using the reference signal;
- and
- a processor configured to detect a frequency error in the information signal, and periodically tune the oscillator to reduce the frequency error.
