Abstract
A spur cancelation system includes error circuitry, inverse spur circuitry, and injection circuitry. The error circuitry is configured to generate an error signal based at least on a first transceiver signal in a transceiver signal processing chain. The inverse spur circuitry is configured to, based at least on the error signal, determine a gain and a phase of a spur signal in the transceiver signal and generate an inverse spur signal based at least on the gain and the phase of the spur signal. The injection circuitry is configured to inject the inverse spur signal to cancel a spur in a second transceiver signal in the transceiver signal processing chain.
