System and method for estimating and correcting phase shift in a wireless communication device
摘要:
In accordance with some embodiments of the present disclosure, a method for estimating and correcting phase shift in a wireless communication device, may include converting a digital signal output by digital circuitry of the wireless communication device into a compensated digital signal based on a calculated phase error. The method may also include converting the compensated digital signal into a wireless communication signal. The method may additionally include calculating an estimated instantaneous reference phase of the digital signal output by the digital circuitry. The method may further include calculating an estimated transmit phase of the wireless communication signal. Moreover, the method may include calculating a phase error based on a difference between the estimated instantaneous reference phase and the estimated transmit phase of the wireless communication signal.
