Abstract
A communication apparatus having a first and second wireless communications modules is provided. The first wireless communications module includes a receiving unit receiving RF signals from an air interface, a signal processing module performing frequency down conversion on the RF signals to generate baseband signals according to a clock signal, and a processor processing the baseband signals. The processor further detects an ON/OFF status of the second wireless communications module to obtain a detection result and compensates for frequency drift of the clock signal according to the detection result.
Claims18
A communications apparatus, comprising:
- a first wireless communications module, arranged to provide a first wireless communications service and comprising:
- a receiving unit, arranged to receive RF signals from an air interface;
- a signal processing module, arranged to perform frequency down conversion on the RF signals to generate baseband signals according to a clock signal;
- and
- a processor, arranged to process the baseband signals;
- and
- a second wireless communications module, arranged to provide a second wireless communications service,
- wherein the processor further detects an ON/OFF status of the second wireless communications module to obtain a detection result, and compensates for frequency drift of the clock signal according to the detection result.
A wireless communications module, arranged to provide a first wireless communications service, comprising:
- a receiving unit, arranged to receive RF signals from an air interface;
- a signal processing module, arranged to perform frequency down conversion on the RF signals to generate baseband signals according to a clock signal;
- and
- a processor, arranged to process the baseband signals,
