    摘要： In RF transceivers, a method and a system for a frequency feedback adjustment in digital receivers are provided. A DC offset may result from the difference in frequencies between an RF transmitter and an RF receiver. An adjustment of the receiver's frequency may be implemented after synchronization occurs and may be performed by, for example, utilizing a header portion of a packet communicated via a wireless interface. The adjustment may be performed when the frequency difference exceeds a threshold value. In another aspect, adjusting the frequency of the RF receiver may be performed by modifying and/or changing a phase locked loop (PLL) trimmer register. This approach may allow an RF receiver to operate, in some instances, without the need for an equalizer. In this regard, the power consumed by the RF receiver may be minimized and/or the overall cost of the RF receiver may be reduced.

    摘要： In RF transceivers, a method and system for using phase shift key (PSK) sync word for fine tuning frequency adjustment are provided. One aspect of the invention provides for adjusting a local oscillator frequency in a radio frequency (RF) receiver when a residual DC offset remains after a coarse frequency offset adjustment if performed. The fine adjustment may be necessary because of the synchronization required with a PSK-based modulated portion of a Bluetooth packet. A residual phase shift detected in a sync sequence portion of the Bluetooth packet may be utilized to determine a residual or fine frequency adjustment. This approach may allow an RF receiver to operate, in some instances, without the need for an equalizer. In this regard, the power consumed by the RF receiver may be minimized and/or the overall cost of the RF receiver may be reduced.
