Abstract
Systems and methodologies are described that facilitate mitigating ringing effects of a voltage-controlled oscillator upon turning on a transmitter. A receiver generates at least one frequency offset estimate subsequent to an antecedent frequency offset estimate that is potentially erroneous due to ringing effects. The receiver extrapolates a phase error on upcoming symbols based upon a delta between the subsequent and antecedent frequency offset estimates. The phase error is employed to correct the upcoming symbol for ringing effects. In addition, the transmitter can detect a packet in advance of being ready for transmission and power up upon detection to allow the ringing to settle.
