REFERENCE OSCILLATOR FREQUENCY CORRECTION SYSTEM |
摘要 |
<p>A receiver reference oscillator frequency correction system and method are described that provides a receiver with a greater ability to lock onto relatively weak radio frequency signals by determining and estimating an amount of frequency error in a local frequency reference of the receiver, and using the error estimate to maintain frequency coherence with a received signal, thereby allowing tracking over a longer period of time, enabling longer integration times to capture weaker signals without losing frequency coherence.</p> |
