摘要： A method, apparatus and system are described for adjusting the frequency of one or more clock signals used by a device. The one or more clock signals are adjusted by a determined amount when a channel quality metric of an RF channel in use by the device indicates a degradation in the reception quality. A radio frequency channel quality metric (RF metric) of a radio frequency channel in use is monitored by a device;
a clock signal used by a clocked component of the device is determined as a target clock signal to adjust when the RF metric violates a threshold;
a clock adjustment is determined to apply to the target clock signal;
a rate of the target clock signal is adjusted according to the clock adjustment;
followed by a step of returning to monitor the RF metric of the radio frequency channel or an RF metric of another radio frequency channel in use by the device.
