Abstract

Systems and methods configured to cancel spurs in a phase locked loop (PLL) system are provided. A method configured to cancel spurs in a PLL system includes receiving a PLL signal from the PLL system; determining an estimated spur frequency of a spur in the received PLL signal based on the received PLL signal; and canceling the spur in the received PLL signal based on the estimated spur frequency.
